Hydrochloric Acid → 4-[({4-[4-Cyclopropyl-2-(2-trifluoromethoxy-phenyl)-2H-pyrazol-3-ylmethoxy]-2-methyl-phenyl}-methyl-amino)-methyl]-2-methoxy-benzoic Acid

Participants

Reaction Steps

A mixture of 4-[({4-[4-cyclopropyl-2-(2-trifluoromethoxy-phenyl)-2H-pyrazol-3-ylmethoxy]-2-methyl-phenyl}-methyl-amino)-methyl]-2-methoxy-benzoic acid methyl ester (0.30 g, 0.51 mmol), sodium hydroxide (5 N, 0.5 mL), THF (3 mL) and methanol (3 mL) is heated to reflux for 1 h. The reaction is cooled and acidified with 5 N HCl, then diluted with water and extracted with ethyl acetate. The combined organic layers are washed with brine and dried over MgSO4 to give the tile compound (285 mg, 97%) as an off-white foam. LC-ES/MS m/e 582.0 (M+1).
