Procedure
A mixture of 2-chloro-6,7-dimethyl-quinazolin-4-ylamine 1 (X=Cl) (900 mg), (1-benzyl-4-phenyl-piperidin-4-ylmethyl)-methyl-amine 2a (R1=CH3 and R2=phenyl) (440 mg) and potassium carbonate (250 mg) in 1-butanol (20 ml) was refluxed for 18 hours. The cooled reaction mixture was filtered, the filtrate was evaporated, and the residue was distributed between water and dichloromethane. The organic phase was dried over potassium carbonate, filtered, and evaporated. The residue was purified by flash chromatography on silica gel to provide 1.3 g of N2-(1-Benzyl-4-phenyl-piperidin-4-ylmethyl)-6,7-dimethoxy-N2-methyl-quinazoline-2,4-diamine 10, as an oil, MS: 485 (M+).
