To (R)-5-(4-(piperidin-3-yl)-1H-1,2,3-triazol-1-yl)-3-(pyridin-4-yl)-1H-indazole (0.075 g, 0.2 mmol) dissolved in MeOH (3 mL) at 0° C. was added 2,6-difluorobenzaldehyde (0.29 g, 2.1 mmol) and then sodium triacetoxyborohydride (0.11 g, 0.5 mmol). The reaction mixture was allowed to warm to room temperature and stirred for 3 h. Evaporated the solvent, subjected to Preparative Thin Layer chromatography to give (R)-5-(4-(1-(2,6-difluorobenzyl)piperidin-3-yl)-1H-1,2,3-triazol-1-yl)-3-(pyridin-4-yl)-1H-indazole (0.025 g).
