Abstract

NEW MATERIAL:The titled derivative expressed by formula I (R1 is halogen, nitro, lower alkoxy or lower alkyl; R2, R3, R4 and R5 are lower alkyls; n is 0W2).
EXAMPLE: O,O-Diethyl O-(2-diethylaminoquinazolin-4-yl)thionophosphate.
USE: An insecticide against injurious and sanitary injurious insects with low toxicity to warm-blooded animals.
PROCESS: A quinazolium-2,4-dione derivative of formula II is reacted with phosphorus oxychloride in the presence of a trialkylamine to form a compound of formula III, which is then hydrolyzed to give a quinazoline derivative of formula IV. The quinazoline derivative is reacted with an alkali metal hydrixide if necessary to afford an alkali metal salt of formula V (M is alkali metal). The compound of formula IV or V is then reacted with a halothionophosphate of formula VI (X is halogen).
