Procedure

To a mixture of the N-(4-chlorobenzyl)-4-hydroxy-6-(3-hydroxy-1-propynyl)-7-methyl[1,8]naphthyridine-3-carboxamide (0.081 g, 0.212 mmol) and potassium carbonate (0.117 g, 0.848 mmol) in 5 mL DMF is added methyl iodide (0.036 g, 0.254 mmol). The mixture is stirred at room temperature for 30 min then diluted with water. The resulting precipitate is filtered and dried. The crude solid is triturated with EtOAc/hexanes to yield 0.072 g (86%) of the desired product as a pale yellow solid. Physical characteristics are as follows: m.p. 217-218° C.; 1H NMR (DMSO-d6) δ10.13, 8.99, 8.46, 7.39, 5.47, 4.55, 4.40, 3.99, 2.75; IR (drift) 3395, 1661, 1604, 1561, 1544, 1503, 1413, 1357, 1261, 1032, 1017, 842, 811, 800, 601 cm1; MS (EI) m/z (rel. intensity) 395 (M+, 8), 255 (29), 229 (17), 228 (99), 198 (41), 169 (14), 140 (54), 89 (15), 77 (14), 73 (22), 73 (17); HRMS (FAB) calcd for C21H18ClN3O3 +H1 396.1115, found 396.1121.
