실험 절차

To a solution of 6-cyclopropylpyridazin-3-amine (50 mg, 0.370 mmol) in pyridine (1 mL), stirred under nitrogen at room temperature, was added 4-((3,5-dimethylisoxazol-4-yl)methoxy)benzene-1-sulfonyl chloride (346 mg, 1.147 mmol). The reaction mixture was stirred at room temperature for 16 hours. The mixture was evaporated and purified by solid phase extraction (SPE) using an aminopropyl (NH2) cartridge with sequential solvents methanol then 2M ammonia/methanol. The appropriate fractions were combined and evaporated in vacuo to give the crude product. The crude was further purified by mass directed autoprep (formic acid modifier). The relevant fractions were removed under a stream of nitrogen to give the title product (51 mg). LCMS (2 min, formic) Rt 0.86 min, m/z (ES+) 401 (M+H).
