Procedure

To a solution of {4-[1-(4-chloro-2-nitro-phenyl)-4-hydroxy-pyrrolidin-3-yl]-piperazin-1-yl}-(4-chloro-phenyl)-methanone (300 mg, 0.64 mmol) in CH2Cl2 (5 mL) at 0° C., was added Et3N (0.2 mL, 1.42 mmol) and acetyl chloride (112 mg, 1.42 mmol). The mixture was stirred at RT for overnight. The organic phase was washed with Saturated NaHCO3, dried over Na2SO4, and concentrated. The residue was purified by column chromatography (Ethyl acetate) to give the desired product (160 mg, 50% yield) as a yellow oil. MS: (ESI), M/Z, 507(M+1). Retention time: 2.59 min (FA-polar).
