A mixture of ethyl 4-(1-(2-methyl-4-(4-(trifluoromethyl)-1H-pyrazol-1-yl)phenoxy)butyl)benzoate (90 mg, 0.2 mmol), lithium hydroxide monohydrate (24 mg, 1.0 mmol), methanol (2 ml), THF (3 ml), and water (1 ml) was stirred at +45° for 18 hours. The mixture was concentrated, diluted with 8 ml of water and 2 ml of 1 M potassium hydrogen sulfate. The mixture was extracted with ethyl acetate-heptane (1:1), extract was washed with brine, dried over anhydrous magnesium sulfate and concentrated to obtain the target product as a white solid (84 mg, 99%). MS (M+1): 419.2.
