A mixture of 3-chloro-6-(3-methylisothiazol-5-yl)pyridazine (0.85 g, 4.0 mmol) and anhydrous hydrazine (3.8 ml, 120 mmol) in 30 mL of sec-BuOH was heated at 130° C. for 3 hours. The mixture was cooled to 23° C. and diluted with 5 mL of water. The solid was collected by filtration and was washed by 2 mL of water to produce a yellow solid. MS (ESI pos. ion) m/z: 208 (MH+). Calc'd exact mass for C8H6ClN3S: 207.
