6-溴-1,3-苯并二口恶茂-4-甲醛的合成

摘要

The 6bromo1,3benzodiozole4carbonaldehyde was synthesized by using 2hydroxy3methoxy benzaldehyde as an original reactant, through three steps of bromination, demethylation and methylenation. The title compound was identified by elemental analysis. IR, 1HNMR and MS. The melting point was 113114℃ determined with macroscope melting instrument and was 113.8℃ determined with DSC.
