The 3-amino-4,5,6,7-tetrahydrobenzo[1,2-b]selenophene-2-carbonitrile is prepared starting from 2-chlorocyclohex-1-enecarbonitrile, sodium selenide and chloroacetonitrile, which on treatment with aqueous sodium hydroxide gave the corresponding amide in good yield. Diazotization of the amine with sodium nitrite followed by treatment with iodomethane in presence of a base gave the required 3-methyl-6,7,8,9-tetrahydrobenzo[1,2-b]1,2,3-triazino-[4,5-d]-selenophen-4-one (compound 14).
