Participants

Reaction Steps

A mixture of Intermediate 58 (137 mg, 0.254 mmol) and morpholine (1.3 mL) was stirred 14 h at room temperature. The mixture was concentrated in vacuo. Chromatography (DCM to 8% 2 M NH3 in MeOH/DCM) afforded the desired product as a pale yellow foam (95 mg, 78%). MS (ESI) mass calculated for C24H27FN8O2, 478.53; m/z found, 479.3. 1H NMR (500 MHz, CDCl3): 7.86-7.78 (m, 2H), 7.72 (s, 1H), 7.51-7.44 (m, 1H), 7.18-7.10 (m, 1H), 5.77-5.72 (m, 1H), 3.99-3.47 (m, 13H), 3.28-3.21 (m, 1H), 3.09-2.91 (m, 2H), 2.90-2.86 (m, 2H), 2.25 (s, 3H).
