Abstract

Optically active C1-C3-alkyl esters of 1-(1-phenylethyl)-1H-imidazole-5-carboxylic acid are prepared by reacting racemic 1-(1-phenylethyl)-1H-imidazole-5-carboxylic acid with an optically active isomer of 1-phenylethylamine, 1-(1-naphthyl)ethylamine or 1-(2-naphthyl)ethylamine. The resulting insoluble diastereomeric salt is separated off and treated with a strong non-oxidising mineral acid. The resulting optically active 1-(1-phenylethyl)-1H-imidazole-5-carboxylic acid is then esterified with a C1-C3-alcohol. In another process, the resulting optically active acid is firstly converted into the acid halide and then correspondingly esterified. The prepared compounds can be used as hypnotics. [GB1535566A]
