Ammonium Acetate → 2-(4-(1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazol-3-yl)phenyl)cyclohexanamine

Participants

Reaction Steps

To a dry flask was added a solution of 2-(4-(1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazol-3-yl)phenyl)cyclohexanone (CB55) (0.98 g, 2.4 mmol) in dry methanol (30 mL). The flask was evacuated/backfilled with nitrogen and ammonium acetate (2.6 g, 34 mmol) was added, followed by sodium cyanoborohydride (0.18 g, 2.9 mmol). The reaction was stirred at room temperature overnight. The solution was quenched with water and extracted with ethyl acetate. The organics were dried, filtered, and concentrated to provide the title compound as a white solid (0.42 g, 34%): 1H NMR indicated the presence of 2 isomers, which were not separated. 1H NMR (400 MHz, DMSO-d6) δ 9.41 (two s, 1H), 8.14-8.03 (m, 4H), 7.66-7.60 (m, 2H), 7.53-7.40 (m, 2H), 3.47-3.16 (br s, 2H), 3.29 (td, J=11.0, 3.8 Hz, 1H), 2.59 (td, J=11.6, 11.1, 3.7 Hz, 1H), 2.17-2.04 (m, 1H), 1.86-1.68 (m, 3H), 1.68-1.30 (m, 4H); ESIMS m/z 402 ([M]+).
