3-((4-(4-Amino-5-chloro-2-ethoxybenzoyl)piperazin-1-yl)methyl)-N-tert-butylbenzamide (250 mg, 0.525 mmol) and 4-nitrophenol chloroformate (425.7 mg, 0.525 mmol) were combined and stirred in dichloromethane for 1 hour. Cyclopropylmethylamine (0.114 g, 1.6 mmol, 0.139 mL) was added and the reaction was stirred for 30 minutes. The reaction mixture was diluted with water and flushed through a hydrophobic frit. The organic phase was concentrated under reduced pressure and purified by basic reverse phase HPLC to give the title compound (9.1 mg).
