Versuchsvorschrift

Hydrazine monohydrate (0.398 mL, 5.24 mmol) was added to 4-chloro-5-ethyl-2-methylpyrimidine (216 mg, 1.31 mmol). The reaction mixture was stirred in a sealed tube at room temperature overnight. Remaining hydrazine was evaporated. Purification by column chromatography (SiO2, methanol/ammonia/dichloromethane) to afforded the desired product (136 mg, 68.2%) as an amorphous off-white solid. MS: m/z=153.11 (M+H+)
