To a solution of acid 225 (220 mg, 0.474 mmol, scheme 54), amine 242 (309 mg, 0.474 mmol) and DIPEA (0.331 mL, 1.895 mmol) in DMF (5 mL) was added HATU reagent (270 mg, 0.710 mmol). The mixture was stirred overnight at room temperature then partitioned between ethyl acetate and water. The organic layer was collected, washed with water, 1M NaOH, and brine, dried over anhydrous MgSO4, filtered and concentrated. The residue was purified by Biotage (MeOH/DCM, 0-15%, SNAP 10 g cartridge) to afford title compound 243 (250 mg, 0.254 mmol, 54% yield) as a white solid. MS: 985.4 (MH+).
