실험 절차
Acid 15B (303 mg, 1 mmol) was dissolved in 5 ml of THF and at rt DEPC (1.1 equiv, 0.17 ml) and [2-[4-(trifluoromethoxy)phenyl]-4-pyridyl]methanamine 21B (1.1 equiv., 295 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 100 mg of a white solid.
