How is 2-Thiophenecarbonitrile (CAS: 1003-31-2) typically synthesized?

2-Thiophenecarbonitrile is typically synthesized by the nitrilation of thiophene. This can be achieved using a variety of methods, including the use of cyanide or cyanamide in the presence of a base, such as sodium hydroxide, at elevated temperatures. The reaction proceeds with good yield and selectivity, making it a reliable method for the synthesis of this compound.
