Procedure
To a solution of 2-(3-(4-(1-((tert-butoxycarbonyl)amino)cyclobutyl)phenyl)-9H-benzo[f]imidazo[1,2-d]pyrido[2,3-b][1,4]diazepin-2-yl)acetic acid (0.04 g, 1 eq.) in dichloromethane (2 mL) was added successively aniline (0.027 g, 4 eq.), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDCI) (0.029 g, 2 eq.) and diisopropylethylamine (70 μL, 5 eq.). The reaction was stirred at room temperature for 20 hours. The reaction mixture was diluted with dichloromethane (10 mL), washed with water (2×10 mL), dried over sodium sulfate, filtered and concentrated under reduced pressure. Purification by preparative HPLC (YMC PACK ODS-AM; AM12S05-1020WT; 100×20 mm ID; CAN/0.1% TFA, 30 mL/min) gave tert-butyl (1-(4-(2-(2-oxo-2-(phenylamino)ethyl)-9H-benzo[f]imidazo[1,2-d]pyrido[2,3-b][1,4]diazepin-3-yl)phenyl)cyclobutyl)carbamate (0.022 g, 48%). LCMS: 613 [M+H].
