Definitions
- New imidazole derivatives their production and their use as intermediates for the production of pharmaceuticals and pesticides
- the present invention relates to new substituted imidazoles of the general formula
- the compounds can be used as intermediates for the preparation of drugs or pesticides. From them, further heterocyclic rings can be attached to the imidazole to build important polycyclic basic structures. They are particularly suitable for the preparation of imidazo [4,5-d] pyridazin-4-ones and imidazo [4,5-c] pyridin-4-ones which e.g. can be used as DPP IV inhibitors in the treatment of diabetes (see e.g. WO 03/104229). Furthermore, broad substituent variations at three positions of the imidazole can be carried out under different reaction conditions, which makes these compounds appear particularly attractive as a basic building block (scaffold) in the synthesis of combinatorial libraries.

- the reactions can also be carried out under microwave radiation.
- the imidazo [4,5-d] pyridazin-4-ones obtained thereafter can be converted into suitable inhibitors of dipeptidyl peptidase IV (DPP IV), for example, by suitable substitution according to methods known per se, which in turn are used in the treatment of diabetes can.
- DPP IV dipeptidyl peptidase IV
- Scheme 2 shows an example of the synthesis of such a compound starting from a compound of general formula I.
- the synthesis sequence begins with the reaction of VI, which is a concrete example of compounds of the general formula I, with hydrazine hydrate in ethanol. After complete reaction of VI with hydrazine to the hydrazone, acetic acid is added and the solution is stirred at 100 ° C. After that, VII becomes in high yield receive. Alkylation of VII with 2- (chloromethyl) -4-methylquinazoline IX in the presence of potassium carbonate in DMF gives X. Alternatively, X can also be synthesized directly from VI with 2- (hydrazinylmethyl) -4-methyl-quinazoline VIII. To do this, proceed as from VI to VII.
- X is then reacted with (R) -3-t-butyloxycarbonylamino-piperidine in DMSO at 70 ° C. to give XI, which is then obtained in good yield.
- the protective group in XI, t-butyloxycarbonyl is split off under acidic conditions, for example with trifluoroacetic acid or alcoholic hydrochloric acid in dichloromethane.
- the DPP IV inhibitor V is thus obtained in consistently high yields in only three or four reaction steps.
