Reaction Steps

Phenylmethanesulfonyl chloride (10.5 g, 55 mmol) was added into a solution of (R)-1-(4-bromophenyl)ethanamine (10 g, 50 mmol) in pyridine (100 mL) drop wise at 0° C. The reaction mixture was stirred at 10° C. for 1 hour. The reaction was poured into water (500 mL), the pH value adjusted to 5 with 6 N aqueous HCl, extracted with EtOAc (100 mL×4). The organic layer was dried over Na2SO4, filtered, and concentrated to provide the title compound (13 g, 73% yield) as pale yellow solid which was used in the next step without further purification.
