Abstract
3-Amino-2-methyl-4(3H)-quinazolinone (2) has been synthesized by treat ing 2-methylbenzoxazinone (1) with hydrazine hydrate. Reaction of quin azolinone (2) with phenyl isothiocyanate and phenyl isocyanate furnish the corresponding aminocarbothiamide and aminocarbamide derivatives ( 3 and 5), respectively, which on reaction with malonic acid in acetyl chloride afford thiobarbituric and barbituric acid derivatives (4 and 6), respectively. Behaviour of compound 5 towards different aldehydes, ketones and imides have been investigated.
