実験手順
4-t-Butyl-2-chloro-6-(methylthiomethyl)aniline (1.3 g) was dissolved in methanol (50 ml) and Raney-nickel (prewashed to pH 7) was added portionwise until t.l.c. indicated all starting material had reacted (ether-hexane, 1:10). The Raney-nickel was removed by filtration through Celite and the filtrate was evaporated. The residue was dissolved in ether and washed with brine, dried (MgSO4) and evaporated. The residue was purified on silica using hexane and 5% ether in hexane as eluent to afford 4-t-butyl-2-chloro-6-methylaniline as a yellow liquid. 1H NMR (360 MHz, CDCl3) δ1.26 (9H, s, (CH3)3), 2.19 (3H, s, CH3), 3.97 (2H, s, NH2), 6.97 (1H, d, J=2.0 Hz, ArH), 7.14 (1H, d, J=2.0 Hz, ArH).
