실험 절차

To a mixture of 4-(trifluoromethyl)-3-pyridinecarbonitrile (9.5 g, 55 mmol, 1.0 equiv) and 5 M NH3 in methanol (600 mL, 3.0 mol, 54 equiv) was added Raney-Ni (3.0 g, 52 mmol, 0.95 equiv). The flask was fitted with a hydrogen balloon, and the mixture was stirred for 16 h. The reaction mixture was filtered, and the filtrate was concentrated. The residue was purified by HPLC to afford 10.5 g (47%) of the title compound as the bis-trifluoroacetate salt. MS (ES+): m/e 177.1 [M+H]+.
