Benzothiazole-2-acetonitrile (750 mg, 4.3 mmol) and 4-cyanobenzaldehyde (564 mg, 4.3 mmol) are dissolved in ethanol (20 ml). Piperidine (11 mg, 0.13 mmol) is added, and the reaction is stirred at room temperature for 2 hours. A precipitate is formed, which is filtered and washed with additional ethanol (5 ml). The solid is dried in a vacuum desiccator overnight and used without further purification.
