The Uses of 2-Methoxybenzonitrile

2-Methoxybenzonitrile was used in the synthesis of 5-(4′-methyl [1,1′-biphenyl]-2-yl)-1H-tetrazole.

Preparation

o-Anisidine with sodium nitrite to make a diazonium salt solution, add it to the lead cyanide solution, and then add benzene. Put the mixture for 10-15h and carry out steam distillation, separate the benzene layer from the distillate, dry it with calcium chloride, evaporate the benzene, and distill the residue under reduced pressure, collect 120-122.5°C (1.2kPa fraction) to get 2-Methoxybenzonitrile, yield 64.5-67.3%.
