Reaction Steps

7-Fluoro-2-[N-[[2-(4-methoxybenzyl)-2-H-[1,2,4]triazol-3-yl]methyl]methylamino]-5-methyl-6-phenyl-1,3-benzoxazole-4-carbonitrile (I-164) (0.33 g, 0.68 mmol) was dissolved in trifluoroacetic acid (5 ml), and stirred at room temperature for 16 hours, then at an external temperature of about 60° C. for 6 hours. The solvent was evaporated away under reduced pressure, then ethyl acetate and aqueous sodium hydrogencarbonate solution were added, and the organic layer was separated. After drying over anhydrous sodium sulfate, the solvent was evaporated away under reduced pressure, and the resulting residue was purified by silica gel column chromatography (dichloromethane:methanol=20:1) to obtain a colorless solid (0.24 g, 97%).
