Reaction Steps
Dissolve 1-(3,5-bis-trifluoromethyl-benzyl)-5-pyridin-3-yl-1H-[1,2,3]triazole-4-carboxylic acid methyl ester (10.0 g) in MeOH (110 mL). Add NaBH4 (2.64 g, 3 eq) and warm to reflux overnight (70° C.). Cool to RT and slowly pour into a separatory funnel containing an equal volume of water; extract with CH2Cl2. Dry the organic layer, concentrate, and recrystallize from EtOAc/Hexanes to give 7.0 g (75%) of the title compound. MS (ES) 403.2 (M+1); 1H NMR: (400 MHz, CD3OD) δ: 8.65 (dd, J=5.2, 1.6 Hz, 1H) 8.53–8.52 (m, 1H), 7.89 (s, 1H), 7.86–7.83 (m, 1H), 7.60 (s, 2H), 7.56–7.53 (m, 1H), 5.83 (s, 2H), 4.59 (s, 2H).
