In the same manner as that described in Example 3(4) a reaction was carried out using commercially available 4-aminobenzonitrile (98 mg, 0.83,mmol), trimethylaluminium (0.78 ml, 1.07M n-hexane solution, 0.83 mmol) and methyl 4-[trans-5-[[(1R,2R)-2-(2,4-difluorophenyl)-2-hydroxy-1-methyl-3-(1H-1,2,4-triazol-1-yl)propyl]thio]-1,3-dioxan-2-yl]-3-fluorobenzoate (109 mg, 0.21 mmol) obtained in Example 5(2) and the reaction mixture was treated using a similar procedure to that described in Example 3(4) to give the title compound (95 mg, yield 75%) as a colorless oil which was recrystallized from ethyl acetate-hexane to give white powdery crystals.
