Procedure

To a 0.25M solution of 2-(2-chloro-4-nitro-phenylsulfanyl)-benzothiazol-5-carboxylic acid (253), (1.38 g, 3.8 mmol) in 10% MeOH in THF was added a 2M solution of (trimethylsilyl)diazomethane in hexane, obtained from Aldrich, (2.1 mL, 4.18 mmol) and the resulting solution was allowed to stir for 18 hours. The crude reaction mixture was concentrated under vacuum to yield 1.4 g (100%) of ester 254 which was taken on without further purification.
