Reaction Steps

(1S,5R,6S)-6-((1R)-1-Hydroxyethyl)-1-methyl-2-(7-methylthioimidazo[5,1-b]thiazol-2-yl)-1-carbapen-2-em-3-carboxylic acid was prepared from sodium (1S,5R,6S)-6-((1R)-1-hydroxyethyl)-1-methyl-2-(7-methylthioimidazo[5,1-b]thiazol-2-yl)-1-carbapen-2-em-3-carboxylate and a 1.0 N aqueous hydrochloric acid solution. The title compound (33.5 mg) was obtained using this compound (103.0 mg), 123.7 mg of benzyltriethylammonium chloride, 113.3 mg of 1-(2ethyl-1-butyloxycarbonyloxy)ethyl chloride, 54.9 mg of triethylamine, and 24 ml of DMF according to the method described in Publication No. 504039/1999 of the Translation of International Patent Application.
