Reaction Steps

To a solution of 1-[1-(4-Chloro-benzoyl)-4-hydroxy-pyrrolidin-3-yl]-piperazin-2-one (50 mg, 0.15 mmol) in CH2Cl2 (1 mL) at 0° C., was added DIPEA (27 uL, 0.154 mmol) and 4-Chloro-benzoyl chloride (20 uL, 0.154 mmol). The mixture was stirred at RT for 4 h. The organic phase was washed with Sat. NaHCO3, dried over Na2SO4, and concentrated. The residue was purified by column chromatography (Ethyl acetate:Methanol:Et3N:10.1:0.1) to give the desired product (36 mg, 50% yield) as a white solid. MS: (ESI), M/Z, 462 (M+1). Retention time: 2.25 min (FA-polar).
