Procedure

{3-[5-(5-isopropyl-2,4-bis-methoxymethoxy-phenyl)-4-(4-methoxy-phenyl)-4H-[1,2,4]triazole-3-sulfonyl]-propyl}-dimethylamine (6.8 g, crude F68-02 in the previous step), ethanol (50 mL) and 3 N hydrochloric acid (50 mL) were placed in a 200 mL eggplant shaped flask and the mixture was stirred at 50° C. for 5 hours. After completing the reaction, the reaction mixture was neutralized with saturated sodium hydrogencarbonate, extracted twice with ethyl acetate. The organic layer was washed 4 times with saturated sodium chloride, dried with sodium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (methylene chloride/methanol), followed by basic silica gel column chromatography (methylene chloride/methanol) to obtain the title compound (F68-03: 1.5 g, 35.7% in 2 steps)
