Abstract

Compounds of the general formula <FORM:0605916/IV(b)/1> in which R1 and R2 are the same or different substituents and represent hydrogen, an alkyl or an alkoxy radical containing 1 or 2 carbon atoms, R3 and R4 are the same or different alkyl radicals containing 1 to 3 carbon atoms or may form part of a saturated ring such as piperidine, a methyl substituted piperidine, morpholine, a methyl substituted morpholine or thiomorpholine are obtained by reacting a benzhydryl halide, e.g. the bromide with an amino ethanol of the formula <FORM:0605916/IV(b)/2> in the presence of an acid binding agent, e.g. an alkali metal carbonate. Either an excess of the aminoalcohol or toluene, xylene, benzene and dibutyl ether may be used as solvents. The reaction is preferably carried out between 100-175 DEG C. Detailed examples are given of the preparation of b -dimethylaminoethyl, b -N-piperidylethyl, b -N-(3-methylpiperidyl) ethyl, b - N - morpholinylethyl, b - diethylaminoethyl, b - di - n - propylaminoethyl - p,p1 - dimethyl and b - methylethylaminoethyl - o - methoxy benzhydryl ether.
