To 2-(3-(4-(1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazol-3-yl)phenyl) propyl)isoindoline-1,3-dione (0.373 g, 0.758 mmol) in a 25 mL vial equipped with a stir bar, Vigreux column, and nitrogen was added methanol (7.6 mL) followed by hydrazine monohydrate (0.110 mL, 2.27 mmol). The reaction was heated to 50° C. The reaction mixture was cooled to room temperature and diluted with dichloromethane. The layers were separated and the aqueous layer was extracted with dichloromethane (2×). The organic layers were washed with sodium hydroxide (1 N, 4×), poured through a phase separator and concentrated. The off-white solid was dried over the weekend at 50° C. at about 25 in.
