실험 절차

To a solution of 4-(3-chloro-phenyl)-6-[(6-chloro-pyridin-3-yl)-hydroxy-(3-methyl-3H-imidazol-4-yl)-methyl]-1H-quinolin-2-one (351 mg, 0.737 mmol) in THF (15 ml) was added a 40% aqueous NaOH (2 ml), benzyltriethylammonium chloride (84 mg, 0.369 mmol) and a solution of methyl iodide (0.078 ml, 1.25 mmol) in THF (4 ml). The reaction mixture was stirred at ambient temperature for 4 hours after which time it was partitioned between CHCl3 and water. The organic layer was washed with brine, dried over MgSO4 and concentrated under vacuum to give the crude product. It was chromatographed on silica gel with MeOH-CHCl3—NH4OH (2:98:0.2 to 5:95:0.5) as eluents to afford the title compound as a white solid (200.3 mg, 0.408 mmol, 55% yield).
