Procedure

A suspension of 6-(3-thienyl)-4-chlorothieno[3,2-d]pyrimidine (220, 65 mg, 0.26 mmol) and hydrazine monohydrate (0.1 mL, 2.1 mmol) in ethanol (1 mL) was heated at reflux for 1 hour. After cooling to room temperature, the solid product was collected by vacuum filtration to give (6-(3-thienyl)thieno[3,2-d]pyrimidin-4-yl) hydrazine hydrochloride (48 mg, 66% yield) as a white solid.
