Procedure
To a solution of 6-methyl-2-cyanopyridine (5 g) and BOC2O in EtOAc was added 10% Pd/C. The reaction mixture was stirred under a balloon of H2 for 24 h, and then filtered through diatomaceous earth and concentrated in vacuo. The crude residue was purified by chromatography on silica gel (EtOAc/hex) to give the title compound as a colorless oil. 1H NMR (d6-DMSO, 400 MHz) δ 7.6 (t, 1H), 7.4 (br s, NH), 7.2 (d, 1H), 7.1 (d, 1H), 4.2 (d, 2H), 2.4 (s, 3H), 1.4 (s, 9H).
