Методика

A suspension of (6-(3-thienyl)thieno[3,2-d]pyrimidin-4-yl)hydrazine hydrochloride (222, 39 mg, 0.14 mmol) and 3-pyridinecarboxaldehyde (20 mg, 0.19 mmol) in ethanol (2 mL) was heated at reflux for 4 hours. After cooling to room temperature, the solid product was collected by vacuum filtration to yield 3-pyridinecarboxaldehyde(6-(3-thienyl)thieno[3,2-d]pyrimidin-4-yl)hydrazone (40 mg, 87% yield) as a yellow solid.
