실험 절차

A mixture of 2-chloro-5-nitro-3-(trifluoromethyl)pyridine (5.25 mmol, 1.19 g), ZnBr2 (1.05 mmol, 0.200 g) and 5% Pt © (1.58 mmol, 0.31 g) in ethyl acetate (50 ml) was stirred for 20 hours under hydrogen atmosphere. The catalyst was filtered off and the solid was washed with warmed ethanol. The solvent was evaporated affording the expected product (0.95 g, yield 92%).
