Abstract
PURPOSE:To obtain the titled compound useful as an antidepressant in high quality and yield, suppressing the formation of by-product, by subjecting o- benzylphenol and a 1,4-dihalogenobutane to etherification, amination and addition salt-forming reaction under specific condition. CONSTITUTION:1mol. of o-benzylphenol is etherified with >=5mol. of a 1,4- dihalogenobutane at 20-80 deg.C in the presence of mono- or dialkyl ethers (e.g. polyethylene glycol) for the prevention of discoloration. 1mol. of the resultant 2-(4-halogenobutoxy)diphenylmethane is aminated with >=10mol. of methylamine in an alcoholic solvent at room temperature - 100 deg.C and the obtained 2-(4- methylaminobutoxy)diphenylmethane is made to react with hydrogen chloride in a solvent such as toluene to obtain the objective compound.
