To a solution of S-phenyl-L-cysteine (5.0 g, 25.4 mmol) in methanol (50 ml) was added acetylchloride (2.7 ml, 38 mmol) and the mixture was refluxed overnight. The solvent was evaporated and the residue was recrystallised from ethyl acetate/methanol (3:1) to yield a white solid (3.81 g, 61%). MS (ISP): 211.9 ([M+H]+).
