実験手順

Acid 4D (289.74 mg, 1 mmol) was dissolved in 10 ml of THF and at rt DEPC (1.1 equiv, 0.15 ml) and [2-pyrrolidin-1-yl-6-[4-(trifluoromethyl)phenyl]-4-pyridyl]methanamine 27A (1.1 equiv., 353.47 mg) were added to the solution. The mixture was stirred at rt overnight then evaporated. The residue was dissolved in AcOEt (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 140 mg of a pale yellow solid. Yield=23.6% 1HNMR (DMSO, 200 MHz) δ 1.09 (3H, t), 1.91 (4H, m), 3.38 (6H, m), 4.40 (2H, d), 5.17 (1H, s), 6.11 (1H, d), 6.34 (1H, s), 7.19 (1H, s), 7.78 (6H, m), 8.28 (2H, d), 8.80 (1H, bt) [M+1] 593.9 (C28H28ClF3N4O3S requires 593.06).
