Reaction Steps

A mixture of 4-[1-(4-trifluoromethylphenyl)-1H-indazol-3-yl]-piperidine-1-carbonitrile of Example 101 (20.0 g, 0.054 moles) and sodium methoxide (12.4 ml of 25% sodium methoxide in methanol 0.054 moles) in methanol (120 ml) was warmed to effect solution and then stirred at ambient temperature for 3 hours. The mixture was poured into H2O, extracted (CHCl3), dried (MgSO4), and concentrated to yield an oil. The oil was triturated with hexane which produced 19 g of a solid. The solid was recrystallized twice from toluene-hexane which yielded 14.2 g (65%) of 4-[1-[4-trifluoromethyl)phenyl]-1H-indazol-3-yl]piperidine-1-carboximidic acid methyl ester, m.p. 113°-115° C.
