実験手順
To a solution of cis-[4-(4-dimethylamino-quinazolin-2-ylamino)-cyclohexylmethyl]-carbamic acid benzyl ester obtained in step B of example 24 (12.1 g, 27.9 mmol) in MeOH (120 mL) was added 10% Pd/C (1.21 g). The mixture was stirred at 50° C. under hydrogen atmosphere for 19 hr, filtered, concentrated, and purified by flash chromatography (NH-silica gel, 66% EtOAc in hexane to 15% MeOH in chloroform) to give N2-(4-aminomethyl-cyclohexyl)-N4,N4-dimethyl-quinazoline-2,4-diamine (6.9 g, 83%) as a yellow solid.
