CATALYTIC HYDROGENATION AND FORMYLATION OF 3-METHYL-4-AMINO-5-NITROSO-2,6-DIOXYPYRIMIDINE OVER PALLADIUM CATALYSTS
A study has been made of hydrogenation of 3-methyl-4-amino-5-nitroso-2,6-dioxypyrimidine into 3-methyl-4,5-diamino-2,6-dioxypyrimidine and formylation of the latter with formic acid.The optimal reaction conditions have been found, which ensure a yield of 3-methyl-4-amino-5-formylamino-2,6-dioxypyrimidine as high as 96percent.
