An efficient conversion of carbonyl compounds (aldehydes and ketones) to nitrile, tetrazole, and urea was developed with the use of a POCl3 and sodium azide mixture using a convergent and microwave method. This is the first report on the direct conversion of ketone to urea. The synthesized compounds were characterized by 1H NMR, 13C NMR, mass and IR spectroscopies and were found to be in agreement
通过使用会聚和微波方法使用POCl 3和叠氮化钠混合物,开发了将羰基化合物(醛和酮)有效转化为腈,四唑和尿素的方法。这是有关酮直接转化为尿素的第一份报告。合成的化合物通过1 H NMR,13 C NMR,质谱和IR光谱进行表征,并且发现与报道的化合物一致。

The present invention relates to a process for producing an alkoxy-(tetrazol-1-yl)benzaldehyde compound represented by Formula (2):
wherein A1 is an alkoxy group, and A2 is a hydrogen atom, alkyl group or fluorine-substituted alkyl group, the process comprising reacting a 1-(alkoxyphenyl)-1H-tetrazole compound represented by Formula (1):
wherein A1 and A2 are as defined above, with hexamethylenetetramine in a sulfonic acid solvent, followed by hydrolysis. According to the present invention, an alkoxy-(tetrazol-1-yl)benzaldehyde compound can be safely and efficiently produced by formylating a 1-(alkoxyphenyl)-1H-tetrazole compound.
