The title compound was prepared from 2,3-diamino-4-picoline (0.246 g, 2 mmol) and isobutyric acid (0.19 ml, 2 mmol) according to the procedure described in Step 1 of Example 9. The crude product was purified by flash chromatography on silica-gel using EtOAc-MeOH (20:1) to give the pure product (0.25 g, 72%) as a tan colored solid. 1H NMR (300 MHz, CDCl3): 8.21 (d, 1H, J=5 Hz), 7.05 (d, 1H, J=5 Hz), 3.40 (m, 1H), 2.71 (s, 3H), 1.55 (d, 6H, J=7 Hz). FAB-MS: m/e 176 (M+H).
