It was found that 6-methyl-2-methylthio-4-cyanomethoxypyrimidine (O-isomer) reacted via the cyano group with ammonia and hydroxylamine to give an amldine and an amidoxime respectively. The O-isomer did not react with either primary or secondary amine

Intramolecular cyclization of hydrazides of (2-alkylthio-3,4-dihydro-6-methyl-4-oxo-3-pyrimidml)acetic acids to 1,2,3,4-tetrahydropyrimido[2,1-c]-1,2,4-triazine-3,6-diones

A method has been developed for the synthesis of 1,2,3,4-tetrahydropyrimido[2, 1-c]-1,2,4-triazine-3,6-diones by intramolecullar cyclization of hydrazides of (2-alkylthio-3,4-dihydro-6-methyl-4-oxo-3-pyrimidinyl)acetic acids in benzylamine.
