To prepare the compound of formula III, the 3,4-dihydro-2H-pyran-2 carboxylic acid sodium salt is hydrogenated to the tetrahydro-pyran-2-carboxylic acid. This compound converted to the acid chloride with oxalyl chloride and is then treated with N-benzyl piperazine. The resultant N-benzyl-N'-(tetrahydropyran-2-carbonyl)piperazine is hydrogenated to giveN-(tetrahydro-pyran-2-carbonyl)piperazine. This compound is reacted with the known compound 4-amino-2-chloro-6,7-dimethoxyquinazoline to give the active drug 2-[ 4-(tetrahydro-pyran-2-carbonyl)piperazinyl]-4-amino-6,7-dimethoxyquinazoline.
