v-Triazolines. Part 41.~1 A new synthesis of 2-alkylquinazolines and 2, 9-dialkylpyrimido4, 5-bindoles

摘要

2-Alkylquinazolines were obtained from amidines by reaction with ammonia. The synthesis has been applied to the preparation of 2, 9-dialkylpyrimido4, 5-bindoles, in a one pot reaction, from 1-alkyl-2-azidoindole-3-carbaldehydes, a secondary amine and aldehydes and reaction with ammonia.
