Synthesis of 6-chlorotetrazolo[1,5-a]quinazoline and 6-chloro-4,5-dihydrotetrazolo[1,5-a]quinazoline

详细

Reaction of 5-aminotetrazole triethylammonium salt and 2-fluoro-6-chlorobenzaldehyde resulted in the formation of 6-chlorotetrazolo[1,5-a]quinazoline instead of the expected azomethine. Hydrogenation of the obtained quinazoline afforded 6-chloro-4,5-dihydrotetrazolo[1,5-a]quinazoline.
