Reaction Conditions

Reaction Steps

Powdered aluminium chloride (6.7 g) was added to a mixture of 2-amino-4,5,3',4'-tetramethoxybenzophenone (8.0 g) and chloroacetonitrile (25 ml), and the mixture was stirred at 100° C. for 2 hours. The reaction mixture was poured into water, and the resulting mixture was extracted with chloroform. The chloroform layer was washed with water and dried over magnesium sulfate. The solvent was evaporated. The residue was subjected to column chromatography on silica gel. The fractions eluted with chloroform/ethyl acetate (=10/1, v/v) gave 2-chloromethyl-6,7-dimethoxy-4-(3,4-dimethoxyphenyl)quinazoline (4.9 g, 52%) which was then recrystallized from acetone.
