実験手順
To a solution of N2-(1-Benzyl-4-phenyl-piperidin-4-ylmethyl)-6,7-dimethoxy-N2-methyl-quinazoline-2,4-diamine 10, (1.3 g) and ammonium formate (2.2 g) in 24 ml methanol and 6 ml water was added 10% Pd-C (250 mg). After stirring under reflux for two hours, the reaction mixture was cooled and filtered through celite®. The filtrate was concentrated to a small volume, made basic with potassium carbonate, and extracted with dichloromethane. The extract was dried over potassium carbonate, filtered, and evaporated. The residue was chromatographed on silica gel to provide 800 mg of 6,7-dimethoxy-N2-(4-phenyl-piperidin-4-ylmethyl)-N2-methyl-quinazoline-2,4-diamine 11 as a white powder, MS: 407 (M+).
