Reaction Steps

To a stirred solution of N-(4-(difluoromethoxy)phenyl)-4-methyl-5-(2-(1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-yl)ethyl)-4H-1,2,4-triazol-3-amine (131 mg, 0.280 mmol) in DCM (2 mL), was added TFA (0.646 mL, 8.39 mmol) and the reaction was stirred at room temperature overnight. Solvents were concentrated and the crude product was purified by preparative HPLC on a Sunfire C18 column (150×19×5.0 m) using a gradient of ACN in 10 mM ammonium acetate (0-100%) to give 5-(2-(1H-indazol-5-yl)ethyl)-N-(4-(difluoromethoxy)phenyl)-4-methyl-4H-1,2,4-triazol-3-amine as off white solid (0.026 g, 23%). 1HNMR: 400 MHz, DMSO-d6: δ 2.96-2.98 (m, 2H), 3.08-3.10 (m, 2H), 3.34 (s, 3H), 7.07-7.09 (m, 3H), 7.27-7.28 (m, 1H), 7.47-7.49 (m, 3H), 7.63 (s, 1H), 8.00 (s, 1H), 8.57 (s, 1H), 12.98 (s, 1H). LCMS: RT 1.322 min; LCMS (ES-API), m/z 385 (M+H).
