To a room temperature solution of 6-[5-isopropyl-3-(2-trifluoromethoxy-phenyl)-3H-[1,2,3]triazol-4-ylmethoxy]-2-methyl-pyridin-3-ylamine (150 mg, 0.369 mmol) in MeOH (6 mL) is added 4-formyl-2-methyl-benzoic acid methyl ester (72 mg, 0.406 mmol), and the mixture is stirred for 10 min. Decaborane (14 mg, 0.0738 mmol) is added. After 2 h, formaldehyde (2.0 mL, 37 wt % in water) is added and the reaction is stirred for 10 minutes. A second portion of decaborane (14 mg, 0.0738 mmol) is added. After 2 h, the reaction is concentrated and the residue is chromatographed (SiO2 40 g, 0% to 20% EtOAc/Hexane to yield 4-[({6-[5-Isopropyl-3-(2-trifluoromethoxy-phenyl)-3H-[1,2,3]triazol-4-ylmethoxy]-2-methyl-pyridin-3-yl}-methyl-amino)-methyl]-2-methyl-benzoic acid methyl ester (156 mg, 73%). 1H NMR (400 MHz, DMSO) δ 7.77-7.72 (m, 1H), 7.70 (d, 2H, J=7.9 Hz), 7.66-7.61 (m, 1H), 7.59-7.53 (m, 1H), 7.46 (d, 1H, J=8.8 Hz), 7.23-7.19 (m, 2H), 6.37 (d, 1H, J=8.4 Hz), 5.27 (s, 2H), 3.95 (s, 2H), 3.79 (s, 3H), 3.28 (sept, 1H, J=6.6 Hz), 2.47 (s, 6H), 2.32 (s, 3H), 1.28 (d, 6H, J=6.6 Hz).
