実験手順

A solution of (4-methoxy-benzyl)-[4-trifluoromethyl-6-(2-trifluoromethyl-phenyl)-pyridin-2-yl]-amine (1.00 g, 2.34 mmol, prepared as described in STEP B above) in MeOH (20 mL) was added, the flask was flushed well with Ar, Pd/C (500 mg, 0.235 mmol, 5% on carbon) was added, and the flask was flushed with Ar and fitted with an H2 balloon. The resulting mixture stirred at room temperature for 4 h. The balloon was removed, the flask was flushed again with Ar, the mixture was filtered through diatomaceous earth, and the filter cake was washed well with MeOH. The filtrate was concentrated in vacuo to yield 4-trifluoromethyl-6-(2-trifluoromethyl-phenyl)-pyridin-2-ylamine as a tan solid. 1H-NMR (400 MHz, CDCl3) δ: 7.81 (d, J=7.6 Hz, 1H), 7.64-7.76 (m, 2H), 7.59 (d, J=7.1 Hz, 1H), 7.25 (s, 1H), 6.79 (s, 1H), 3.22 (br. s., 4H).
