Reaction Steps

To a stirring mixture of 2-(4-(3-(piperidin-1-yl)propoxy)phenyl)acetic acid (800 mg) in DMF/DCM (6 mL, 1:1) was added triethylamine (1.2 mL), DMAP (180 mg), 2-amino-4-methylthiophene-3-carboxamide (440 mg), and EDCI (1.1 g). The reaction mixture was stirred at rt overnight, quenched with saturated NaHCO3 solution and extracted with EtOAc. The organic layers were dried over MgSO4, filtered, and concentrated under reduced pressure. The crude product was purified via preparative HPLC to give 4-methyl-2-(2-(4-(3-(piperidin-1-yl)propoxy)phenyl)acetamido)thiophene-3-carboxamide. Method[7], MS(ESI) 416.2 [M+H], Retention time=2.254 min.
