実験手順

To a solution of methyl 3-(3-methyl-3H-imidazo[4,5-f]quinolin-2-yl)butanoate (560 mg, 1.97 mmol) in acetonitrile (20 mL) and water (8 mL) was added lithium hydroxide hydrate (249 mg, 5.94 mmol). The mixture was stirred at room temperature overnight. The mixture was concentrated to about 8 mL. The pH of the solution was adjusted to ˜4 with 1N HCl aqueous solution. The mixture was concentrated to dryness and to the residue was added 50 mL of DCM/MeOH v/v 10:1. The precipitate was removed by filtration and the filtrate was concentrated to dryness to give the product as a yellow solid (480 mg, 90% yield). ESI MS: m/z 270.1 [M+H]+.
