Reaction Steps
To 2-(3-(4-(1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazol-3-yl)phenyl)propyl)isoindoline-1,3-dione (C59) (0.373 g, 0.758 mmol) in a 25 mL vial equipped with a stir bar, Vigreux column, and nitrogen was added methanol (7.58 mL) followed by hydrazine monohydrate (0.110 mL, 2.27 mmol). The reaction was heated to 50° C. until determined to be complete by LCMS. 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 resultant solid was dried in vacuo over 72 hours at 50° C. to provide the title compound as an off-white solid (0.262 g, 95%): 1H NMR (400 MHz, DMSO-d6) δ 9.38 (s, 1H), 8.10-8.04 (m, 2H), 8.04-7.98 (m, 2H), 7.66-7.59 (m, 2H), 7.35 (d, J=8.1 Hz, 2H), 2.69-2.63 (m, 2H), 2.56 (t, J=6.9 Hz, 2H), 1.74-1.59 (m, 2H), (NH2 not observed); 19F NMR (376 MHz, DMSO-d6) δ −56.96; ESIMS m/z 363 ([M+H]+).
