(3,4-Dimethoxyphenyl)acetonitrile has been used in the synthesis of (Z)-3-(benzo[b]thiophen-2-yl)-2-(3,4-dimethoxyphenyl)acrylonitrile. It has also been used in the preparation of modified diterpene (±) nimbidiol which relies on a sulfenium ion promoted polyene cyclization.Purification Methods
Its solubility is 10% in MeOH, and it has been recrystallised from EtOH or MeOH. Purify it also by distillation followed by recrystallisation.
