Reaction Steps

To a solution of L-isoleucine methyl ester hydrochloride (1.82 g, 10 mmol) and 4-chlorobenzenesulfonyl chloride (2.11 g, 10 mmol) in CH2Cl2 was added triethylamine (4.18 mL, 30 mmol). The mixture was stirred at 25° C. for 16 hours, then filtered and concentrated. The crude product was purified by flash chromatography over silica gel using 10% ethyl acetate in hexane to give N-4-chlorobenzenesulfonyl L-isoleucine methyl ester 3.53 g.
