Reaction Conditions

Reaction Steps

To a solution of 6-methoxypyridazin-3-amine (125 mg, 1.0 mmol) in pyridine (8 mL) at room temperature, was added 4-{[(3,5-dimethyl-4-isoxazolyl)methyl]oxy}benzenesulfonyl chloride (0.302 g, 1.0 mmol). The reaction mixture was stirred at 20° C. for 18 hours. The solvent was evaporated in vacuo and passed through an aminopropyl (NH2) solid phase extraction (SPE) cartridge eluting with methanol, followed by a sulphonic acid (SCX) SPE cartridge eluting with methanol. The crude was then purified by flash silica (Si) chromatography (0-100% ethyl acetate-cyclohexane+0-25% methanol gradient), to provide the title compound (16 mg). LCMS (2 min, formic) Rt 0.83 min, m/z (ES+) 391 (M+H).
