Participants

Reaction Steps

A microwave tube was charged with 1G (30 mg, 0.085 mmol), N1,N1-diethylbenzene-1,4-diamine (139 mg, 0.85 mmol), and NMP (1 mL). The mixture was irradiated in a microwave for three cycles of 15 min. (300W), 120° C. The crude reaction mixture was dissolved in a small amount of MeOH and purified by reversed phase HPLC (YMC ODS-A 5 um 30×250 mm, 10-90% aqueous methanol containing 0.1% TFA, 25 mL/min., 30 min. gradient, monitored at 220 nm) to afford 244A, (5 mg, 9.0% yield). HPLC: Rt=3.896 min. (YMC S5 ODS 4.6×50 mm, 10-90% aqueous methanol containing 0.2% H3PO4, 4 min. gradient, monitored at 220 nm). MS (ES): m/z=482.1 [M+H]+.
