Procedure

A mixture of 3-cyano-2,5-di(4-pyridyl)thiophene (40 mg, 0.152 mmol), potassium hydroxide (25 mg, 0.446 mmol) in 2-methyl-2-propanol (2 mL) was heated at reflux temperature for 2 hours. After cooling, the mixture was poured into water. The precipitates were collected by filtration, and dried under reduced pressure to give the title compound (30 mg, 70% yield).
