실험 절차

A mixture of 1.527 g of the syn isomer of sodium 2-(2-tritylamino-4-thiazolyl)-2-trityloxyimino-acetic acid, 419 mg of tosyl chloride and 15 ml of methylene chloride was stirred for 40 minutes and then a solution of 342 mg of 4-chloromethyl-3-amino-2-oxo-azetidine hydrochloride in 15 ml of methylene chloride and 0.6 ml of triethylamine was added thereto. The mixture was stirred for 2 hours and water was added thereto with stirring. The decanted aqueous phase was extracted with methylene chloride and the combined organic phases were dried, filtered and evaporated to dryness under reduced pressure. The residue was chromatographed over silica gel and was eluted with ether to obtain 736 mg of syn isomer of 4-chloromethyl-3-[2-(2-tritylamino-4-thiazolyl)-2-trityloxyimino-acetamido]-2-oxo-azetidine.
