Procedure

To a solution of the product of Step C (60 mg, 0.30 mmol) in DCM (3 mL) was added Intermediate 23 (65 mg, 0.30 mmol) followed by EDCl (85 mg, 0.44 mmol), HOBt (60 mg, 0.44 mmol) and TEA (0.08 mL, 0.59 mmol). The mixture was stirred at room temperature for 14 h and then concentrated in vacuo. Chromatography (DCM to 8% 2 M NH3 in MeOH/DCM) afforded the desired compound as a colorless foam (49 mg, 41%). MS (ESI) mass calculated for C21H23N7O2, 405.19; m/z found, 406.2. 1H NMR (500 MHz, CDCl3): 8.82-8.75 (m, 1H), 8.42-8.36 (m, 1H), 7.52-7.47 (m, 1H), 6.31-6.26 (m, 1H), 4.02-3.90 (m, 2H), 3.86-3.79 (m, 1H), 3.76-3.69 (m, 2H), 3.66-3.54 (m, 2H), 3.24-3.18 (m, 1H), 3.14-2.99 (m, 2H), 2.48-2.42 (m, 3H), 2.33-2.24 (m, 6H).
