Reaction Conditions

Reaction Steps

To a solution of 2.0 g (8.64 mmol) of (S)-N-(1-methyl-2-phenylethyl)trifluoroacetamide (15) in 200 mL of chloroform was added 24 mL of chlorosulfonic acid dropwise at 0° C. The mixture was stirred at 0° C. for 4 hours. The reaction mixture was poured into 100 mL of ice water and extracted with 3×200 mL of chloroform. The organic layers were combined, dried over anhydrous sodium sulphate and evaporated to yield 2.58 g (7.82 mmol, 90%) of (S)-4-[2-[(trifluoroacetyl) amino]propyl]-benzenesulfonyl chloride (16) as a white solid. NMR, IR and MS data confirmed compound identity.
