(54) СПОСОБ ПОЛУЧЕНИЯ АРЕНСУЛЬФОНИЛАМИДОВ ОКСАМИНОВЫХ КИСЛОТ(54) METHOD FOR OBTAINING ARENSULPHONYLAMIDES OF OXAMINE ACIDS
амина, как только среда перестанет быть щелочной, большую часть метанола отгон ют, раствор ют остаток в 5-кратном количестве воды, фильтруют, подкисл ют фильтрат сол ной кислотой (1:1) до , фильтруют, кристаллизуют осадок и получают 4,52 г продукта.amine, once the medium is no longer alkaline, most of the methanol is distilled off, the residue is dissolved in 5 times the amount of water, filtered, the filtrate is acidified with hydrochloric acid (1: 1) to filtered, the precipitate crystallizes and 4.52 g are obtained product.
Пример 2. Изобутиламид п-толуолсульфонилоксаминовой кислоты.Example 2. P-toluenesulfonyloxamic acid isobutylamide.
В тех же услови х, что и в примере 1, после нагревани до исчезновени малинового окрашивани большую часть метанола отгон ют, раствор ют остаток в 5-кратном количестве воды, фильтруют , подкисл ют фильтрат сол ной кислотой (1:1) до рН 5, отфильтровьшают осадок, кристаллизуют и получают 3,4 г этилового эфира п-толуолсульфонилоксаминовой кислоты.Under the same conditions as in Example 1, after heating until the crimson color disappears, most of the methanol is distilled off, the residue is dissolved in 5-fold amount of water, filtered, the filtrate is acidified with hydrochloric acid (1: 1) to pH 5 The precipitate is filtered off and crystallized to obtain 3.4 g of p-toluenesulfonyloxamic acid ethyl ester.
К раствору 3,4 г полученного вещества в 10 мл этанола прибавл ют 1,83 г изобутиламина, как только среда перестанет быть щелочной, большую часть этанола отгон ют, поступают, как в примере 1, и получают 3,04 г целевого продукта.To a solution of 3.4 g of the obtained substance in 10 ml of ethanol was added 1.83 g of isobutylamine, as soon as the medium ceased to be alkaline, most of the ethanol was distilled off, proceeded as in Example 1, and 3.04 g of the desired product are obtained.
В примерах 1 и 2 выход целевого продукта дан в пересчете на вз тый в реакцию п-толуолсульфамид .In Examples 1 and 2, the yield of the desired product is given in terms of the p-toluenesulfamide reacted.

| SU427016A1 (en) | METHOD FOR OBTAINING 4H-3,1-BENZOXAZIN-4-OH-2-CARBIC ACID AMIDES1 The invention relates to the preparation of the 4H-3,1-benzoxazin-4-one-2-amides - carboxylic acid. These amides are not described in the literature, their method of preparation is not known. Chemically, they are highly active compounds and are of interest as intermediates for organic sietez, including for the production of biologically active compounds. In particular, on the basis of these amides, amides of 4 (3H) -quinazolo; n-2-carboxylic acid can be obtained, which, according to literature data, represent HiHTOpec as drugs with P-vitamin activity. In the literature A 4N-3, .1-benzoxazn-4-one-2-carboxylic acid ester preparation method is known to react oxamoyl anthranilic acid ethyl ester with acetic anhydride, followed by isolation of the products by a known method. However, the 4H-3,1-benzoxazium-4-one-2-carboxylic acid amides, as the method of their preparation, were not previously known. A method for preparing the 4H-3,1-benzoxazip-4-one-2-carboxylic acid amides is proposed. of the general formula ICONHR10, where R is hydrogen, normal or isoalkyl, consisting in the fact that the amide of oxamoyl anthranilic acid of the general formula . Methylamide 4H-3,1-benzoxazip-4-one-2-carboxylic acid. 8 g of 1M-1 methyl-ox-M'OIyl "tra". Methyl acid (II, R-CH3) in 16 ml of acetic angndrum is heated under reflux. After 10 minutes from the start of heating, the acid is completely dissolved, heating is continued for another 10 minutes. Upon cooling, a precipitate is released. To the reaction mass was added 10 ml of absolute ether. Sediment filter | |
