In a 250 mL round-bottomed flask, 6-azido-N,N-dimethylnicotinamide (2.26 g, 11.8 mmol) was combined with ethyl acetate (50 ml) and methanol (30 ml) to give a yellow solution. 10% Pd/C (200 mg, 1.88 mmol) was added and the reaction mixture was evacuated and filled with H2 twice. The reaction mixture was stirred under balloon pressure of H2 at 25° C. for 17 h. The reaction mixture was filtered through celite and the filter cake was washed with MeOH. The filtrate was concentrated in vacuo and the cream colored solid was dried under vacuum at 45° C. for 3 hrs to give the title compound in quantitative yield. (M+H)+=166 m/e. 1H NMR (300 MHz, CHLOROFORM-d) δ: 8.21 (d, J=2.3 Hz, 1H), 7.59 (dd, J=8.3, 2.3 Hz, 1H), 6.50 (d, J=8.7 Hz, 1H), 4.69 (br. s., 2H), 3.08 (s, 6H).
