Procedure

In 15 ml of methylene chloride is dissolved 1.445 g of 2-(2-chloroacetamido-4-thiazolyl)-(Z)-2-[1-methyl-1-(p-nitrobenzyloxycarbonyl)ethyloxyimino]acetic acid and under ice-cooling and stirring 686 mg of phosphorus pentachloride is added. The mixture is stirred under ice-cooling for 30 minutes, after which 4.5 ml of hexane is added. The resultant crystalline precipitate is collected by filtration and washed with hexane to give 2-(2-chloroacetamido-4-thiazolyl)-(Z)-2-[1-methyl-1-(p-nitrobenzyloxycarbonyl)-ethyloxyimino]acetyl chloride hydrochloride, m.p. 79°-82° C.
