Procedure

To a suspension of 8A (300 mg, 0.920 mmol) in NMP (2 mL) was added (4-methoxyphenyl)methanamine (0.120 mL, 0.920 mmol) and DIEA (0.161 mL, 0.920 mmol). The reaction mixture was stirred at 80° C. for 1 h, and then cooled to room temperature. Water was added. The light yellow solid was collected by filtration, rinsed with water and dried under vacuum to give 19A (348 mg, 89%). [M+H]=426. HPLC Peak Rt=3.000 minutes. (Chromolith column 4.6×50 mm eluting with 10-90% aqueous methanol over 4 minutes containing 0.1% TFA, 4 mL/min, monitoring at 254 nm.)
