PROCEDURE

实验过程

A mixture of 3,4,5-trichloropyridazine (Preparation 3, 500 mg, 2.73 mmole) in EtOH (5.5 mL) and NH4OH (5.5 mL) was heated under microwave irradiation 120° C. for 25 minutes. Concentration under reduced pressure and purification via silica gel column chromatography eluting with acetone:dichloromethane (0-15% acetone), provided the title product in 36% yield, 163 mg.
