t-butyl 6-(3-cyano-1H-pyrrol-1-yl)pyridazin-3-yl((1-(3-fluoropyridin-2-yl)cyclobutyl)methyl)carbamate (120 mg, 267 μmol), potassium carbonate (147 mg, 1.1 mmol), and DMSO (3 mL) were combined in a vial and cooled to 0° C. Hydrogen peroxide (700 uL) was added dropwise, and the reaction was warmed to rt and stirred for 1 h. The reaction was then poured into ethyl acetate (50 mL), washed with water (3×20 mL), and the organic layer was separated, dried over Na2SO4, filtered, and concentrated. The crude solid was dissolved in 50% TFA/CH2Cl2 (2 mL) and stirred for 30 min. The reaction was then concentrated and purified using reverse phase chromatography to give 29 mg of 1-(6((1-(3-fluoropyridin-2-yl)cyclobutyl)methylamino)pyridazin-3-yl)-1H-pyrrole-3-carboxamide as a tan solid (M+H=367.1).
