실험 절차

Hydrogen chloride gas was bubbled into 2-tert-butyl-5-(3-(5-(1,5-dimethyl-1H-pyrazol-3-ylamino)-6-oxo-1-((2-(trimethylsilyl)ethoxy)methyl)-1,6-dihydropyridazin-3-yl)-2-methylphenyl)-4H-pyrrolo[3,4-d]thiazol-6(5H)-one 110c (186 mg, 0.30 mmol) and anisole (0.163 mL, 1.50 mmol) in methanol (20 mL) at 0° C. for 5 min. The resulting mixture was allowed to warm to room temperature and continue stirring for 16 h. The reaction mixture was concentrated. The residue was purified by reverse phase HPLC: C-18 column eluted with 20 to 60% Acetronitrile in water with 1% ammonium hydroxide over 14 min to afford 2-tert-butyl-5-(3-(5-(1,5-dimethyl-1H-pyrazol-3-ylamino)-6-oxo-1,6-dihydropyridazin-3-yl)-2-methylphenyl)-4H-pyrrolo[3,4-d]thiazol-6(5H)-one 110 (40 mg, 30%).
