3-((4-(4-Amino-5-chloro-2-methoxybenzoyl)piperazin-1-yl)methyl)-N-tert-butylbenzamide (1.712 g, 0.0037 mol) and 4-nitrophenol chloroformate (0.7518 g, 0.0037 mol) were combined and stirred at room temperature in dichloromethane for 1 hour. Isobutylamine (0.1536 g 0.208 mol) was added and the reaction was stirred for a further 30 minutes. The reaction mixture was diluted with water and flushed through a hydrophobic frit. The organic phase was concentrated under vacuum and purified by acidic reverse phase HPLC affording the title compound (37 mg).
