실험 절차

Intermediate A (189 mg, 1.16 mmol) was added to a suspension of sodium hydride (60% in mineral oil, 139 mg, 3.48 mmol) in DMF (5 mL). The reaction was stirred for 20 mins, then Intermediate 1b (292 mg, 1.16 mmol) was added in DMF (5 mL) and the reaction heated to 60° C. for 2 h. The mixture was cooled and quenched by dropwise addition of MeOH. The solution was loaded onto an SCX-2 cartridge, which was washed with MeOH and product eluted with 2M NH3 in MeOH. The residue was purified by FCC using 0-10% [2M NH3 in MeOH] in DCM to give the title compound (270 mg, 0.74 mmol, 64%). 1H NMR (400 MHz, d4-MeOD): 1.80-1.86 (4H, m), 1.92-2.02 (1H, m), 2.05-2.18 (2H, m), 2.30-2.40 (1H, m), 2.62-2.70 (4H, m), 2.99-3.05 (2H, t, J 7.8), 3.28-3.36 (2H, t, J 7.8), 3.98-4.04 (1H, dd, J 8.6, 5.2), 5.46-5.50 (1H, t, J 4.3), 7.22-7.40 (4H, m), 7.54-7.58 (1H, d, J 7.8), 7.63-7.68 (1H, dd, J 9.8, 0.7), 7.97 (1H, s), 8.09-8.11 (1H, d, J 1.6).
