Procedure
To a solution of {4-[2-(2-tert-butoxycarbonylamino-phenylcarbamoyl)-vinyl]-phenyl}-hydroxy-acetic acid methyl ester (9.00 g, 21.1 mmol) and triethylamine (3.20 g, 31.6 mmol) in CH2Cl2 (135 mL) cooled to −5 degrees Celsius was added dropwise methanesulfonyl chloride (3.14 g, 27.4 mmol) under N2 atmosphere. The reaction was stirred at 0 degrees Celsius until the starting material had been consumed according to TLC (about 1 hour). The mixture was washed with water (90 mL) and brine (90 mL), dried with MgSO4, filtered, and evaporated in vacuo to obtain 11.2 g (quantitative yield) of light yellow crystal which was used without further purification. MS: calc'd 505 (MH+), exp 505 (MH+).
