Participants

Reaction Steps

To a solution of (S)-tert-butyl 1-(4-(hydroxymethyl)phenyl)ethylcarbamate (503 mg, 2 mmol) in DCM (10 mL) was added methanesulfonyl chloride (275 mg, 2.4 mmol) and triethylamine (0.56 mL, 4 mmol). The solution was stirred for 16 h at room temperature then washed with water and brine. After separation, the organic phase was dried over Na2SO4, filtered and concentrated. Silica gel column chromatography (EtOAc/heptane 0 to 80%) provided (S)-tert-butyl 1-(4-(chloromethyl)phenyl)ethylcarbamate as a white solid (254 g, 47.1% yield).
