Reaction Steps

Combine 3,6-dichloro-4,5-dimethyl-pyridazine (100 mg, 0.554 mmol), (R)-2-methylpiperazine (85 mg, 0.831 mmol), potassium carbonate (383 mg, 2.77 mmol) and DMF (1 mL) in vial. Heat in the microwave at 120° C. for 3.25 h. Add 2-chloro-5-trifluoromethylpyridine (181 mg, 0.997 mmol) and heat at 180° C. for 30 min. The crude reaction is purified directly by flash chromatography on silica gel (0-40% EtOAc in heptanes) to afford the title compound as a light yellow solid (78 mg, 37%).
