To a solution of 2-cyano-4-hydroxymethylpyridine (step 1, 3.63 g, 27.06 mmol) in DMF (50 ml) were added imidazole (4.42 g, 64.95 mmol) and TBDMSCl (4.89 g, 32.47 mmol) at room temperature. After stirring for 1 h, the mixture was diluted with diethyl ether (300 ml), washed with water (100 ml×4), and dried (MgSO4). Removal of solvent gave the title compound. 1H-NMR (CDCl3) δ: 8.65 (1 H, d, J=5.1 Hz), 7.68 (1 H, s), 7.46 (1 H, d, J=4.9 Hz), 4.78 (2 H, s), 0.96 (9 H, s), 0.13 (6 H, s).
