Abstract Reaction of 2-amino-4, 5, 6, 7-tetrahydro-1-benzoselenophene-3-carbonitrile with ethylenediamine in the presence of a catalytic amount of carbon disulfide afforded 2-amino- 3-(4, 5-dihydro-1 H-imidazol-2-yl)-4, 5, 6, 7-tetrahydro-1-benzoselenophene. Cyclocondensation of the latter with triethyl orthoformate, benzaldehyde, and carbon disulfide gave tetracyclic imidazobenzoselenophenopyrimidine derivatives. Treatment of 2 ...
