Reaction Steps

To a solution of 1-((5-(3-chlorophenyl)-6-(difluoromethoxy)pyridin-3-yl)methyl)-1H-1,2,4-triazol-3-amine (Example 219, 120 mg, 0.34 mmol) in DCM (2 mL), was added formaldehyde (26 μL of 37 wt % solution, 0.35 mmol), sodium triacetoxyborohydride (145 mg, 0.68 mmol) and a few drops of AcOH. The mixture was stirred at room temperature for 16 h. Purification by reverse-phase PREP-HPLC gave the title compound (25 mg, 20%). 1H NMR (400 MHz, CD3OD) δ 8.19-8.11 (m, 1H), 7.82 (d, J=2.0 Hz, 1H), 7.71 (s, 1H), 7.53 (s, 1H), 7.47 (s, 1H), 7.41-7.28 (m, 3H), 5.21 (s, 2H), 2.72 (s, 3H). [M+H]=366.21.
