Procedure

1-(tert-Butoxycarbonyl)-4-(2-(dimethylamino)ethyl)piperidine-4-carboxylic acid from step B (100 mg, 0.33 mmol), HATU (175 mg, 0.46 mmol), and N,N-diisopropylethylamine (0.116 mL, 0.67 mmol) were stirred in isopropyl acetate for 10 minutes. 3-aminophenyl dimethylcarbamate (90 mg, 0.5 mmol) was added, and the reaction was stirred at 85° C. for 2 hours, cooled to room temperature, stirred overnight, and then diluted with EtOAc, washed with sat. aq. Na2CO3 and brine (with back extraction), dried over MgSO4, filtered, and concentrated under vacuum, to give the title compound as a viscous oil. MS (ES+) [M+H]+=463.
