Cyanoselenoacetamide reacts with hydrogen sulfide to form propane-bis(thioamide), which can be used to produce thiazoles (the Hantzsch synthesis) and 3-thioxo-1-phenyl-2,3,5,6,7,8-hexahydroisoquinoline-4-carbonitrile. From the latter compound, 2-alkylsulfanyl-1-phenyl-5,6,7,8-tetrahydroisoquinoline-4-carbonitriles and 1-amino-N-(4-bromophenyl)-5-phenyl-6,7,8,9-tetrahydrothieno[2,3-c]isoquinoline-2-carboxamide can be prepared.
