Procedure

To a solution of 2-(2-amino-4-chloro-phenoxy)-1-[4-(4-fluoro-benzyl)-(2R)-2-methyl-piperazin-1-yl]-ethanone (0.14 g, 0.36 mmol) in dichloromethane (5 mL) was added pyridine (0.032 mL, 0.39 mmol) and 4-nitrophenyl chloroformate (0.079 g, 0.39 mmol). The reaction was stirred at ambient temperature for one hour and concentrated in vacuo to give the title compound (0.20 g).
