Reaction Steps

To an ice-cold solution of 2-amino-4-(4-piperidinyl)quinazoline (600 mg, 2.63 mmol) obtained in example 11(1), 3,4-dihydroxyphenylacetic acid (530 mg, 3.16 mmol) and 4-dimethylaminopyridine (386 mg, 3.16 mmol) in dimethylformamide (20 ml) was added 1-ethyl-3-(N,N'-dimethylaminopropyl)carbodiimide hydrochloride (605 mg, 3.16 mmol) under a nitrogen atmosphere. The mixture was stirred overnight at room temperature. The solvent was removed in vacuo and the residue was crystallized from methanol to give the titled compound (599 mg).
