Abstract
NEW MATERIAL:A compound expressed by formula I [R1 and R3 are lower alkyl; R2 is alkoxycarbonyl; R1, R2 and R3 are linked to the 5W7 or the 6W8 -positions of the quinazoline nucleus; X is alkylene; R5 is H or alkyl; R6 is R5, phenyl, benzyl or formula II (Y is the same as X; R7 is alkyl; R8 is R7 or benzyl, R7 and R8 together with the nitrogen atom form a pyrrolidine ring, etc.); R4 is H, halogen, alkyl, etc.].
EXAMPLE: 1-[ 2-(N,N-Diethylamino)ethyl ]aminocarbonylmethyl-6-ethoxycarbonyl- 5,7-dimethyl-3-(o-chlorophenyl)-2,4(1H,3H)-quinazolinedione.
USE: A vasodilator, an ameliorant of blood flow, a hypotensive agent or antiarteriosclerotic agent.
PROCESS: A compound expressed by formula III is reacted with a compound expressed by formula IV (Z is halogen) in the presence of an alkali metallic hydride or alkali metallic amide to give the compound expressed by formula I.
