Reaction Steps

To a solution of trans-{4-[(4-dimethylamino-quinazolin-2-ylamino)-methyl]-cyclohexyl}-carbamic acid benzyl ester obtained in step C of example 3 (330 mg, 0.76 mmol) in MeOH (3.3 mL) was added 10% Pd/C (33 mg). The mixture was stirred at ambient temperature under hydrogen atmosphere for 25 hr, filtered, concentrated, and purified by flash chromatography (NH-silica gel, 50% EtOAc in hexane) to give trans-N2-(4-amino-cyclohexylmethyl)-N4,N4-dimethyl-quinazoline-2,4-diamine (250 mg, 98%) as a pale yellow oil.
