실험 절차

Acid 15C (260 mg, 1 mmol) was dissolved in 5 ml of THF and at rt DEPC (1.1 equiv, 0.17 ml) and [2-pyrrolidin-1-yl-6-[4-(trifluoromethoxy)phenyl]-4-pyridyl]methanamine 27C (1.1 equiv., 371 mg) were added to the solution. The mixture was stirred at rt overnight then evaporated. The residue was dissolved in EtOAc (30 ml) and washed with water (1×20 ml) and brine. The organic phase was dried over sodium sulfate and concentrated under vacuum. The purification of the crude by chromatographic column (3:7 EtOAc:Petroleum ether) afforded 130 mg of a white solid. Yield=22% 1HNMR (DMSO, 200 MHz) δ 0.71 (2H, bm), 1.08 (2H, bm), 1.92 (4H, m), 3.47 (4H, m), 4.29 (2H, d, J=5.6 Hz), 6.41 (1H, s), 7.09 (1H, s), 7.45 (4H, m), 7.82 (2H, m), 8.17 (2H, d, J=9 Hz), 8.38 (1H, t), 8.71 (1H, bs) [M+1] 579.4 (C27H26F4N4O4S requires 578.58).
