Reaction Steps

Material from step F (9 mg, 0.016 mmol) is placed in a reaction vial and dissolved in 2 ml of a 1:1 THF:i-PrOH mixture. Morpholine (0.08 mmol) is added at r.t, and the sealed vial is heated in an oil bath at 80° C. Reaction progress at 80° C. is followed by LC/MS, and the reaction is stopped after reaching 90% conversion (3 hours). Chromatography of the crude on silica (MeOH/EtOAc) affords pure desired product (1.8 mg, 20%). MS ESI (+) m/z 560 (M+1) detected; 1H NMR (400 MHz, deuterated acetone containing 10% deuterated methanol) δ 8.58 (s, 1H), 8.55 (s, 1H), 8.39 (s, 1H), 8.11 (s, 1H), 7.84-7.76 (m, 4H), 7.65 (d, 1H), 7.37 (q, 1H), 7.12 (d, 1H), 7.04 (m, 2H).
