실험 절차
A suspension of 4-chloro-7-methylthieno[3,2-d]pyrimidine (4, 3.1 g, 17 mmol) and hydrazine monohydrate (3.5 mL, 72 mmol) in ethanol (34 mL) was heated at reflux for 1 hour. After cooling to room temperature, the solid product was collected by vacuum filtration to give (7-methylthieno[3,2-d]pyrimidin-4-yl)hydrazine hydrochloride (3.2 g, 88% yield) as a white solid.
