실험 절차

A mixture of the crude ethyl 2-(4-(3-carbamoyl-4-(((3S,4S)-1-(5-cyanopyridin-2-yl)-4-methylpyrrolidin-3-yl)amino)pyrrolo[1,2-b]pyridazin-6-yl)-1H-pyrazol-1-yl)acetate from Step 1, a 2 N aqueous solution of NaOH (0.5 mL), methanol (0.5 mL) and tetrahydrofuran (0.5 mL) was stirred at room temperature for 1 h. The organic solvents were evaporated in vacuo. The aqueous residue was treated with 1 N HCl (1 mL) and water (1 mL) and filtered. The filter cake was washed with water and dried under vacuum to give crude 2-(4-(3-carbamoyl-4-(((3S,4S)-1-(5-cyanopyridin-2-yl)-4-methylpyrrolidin-3-yl)amino)pyrrolo[1,2-b]pyridazin-6-yl)-1H-pyrazol-1-yl)acetic acid as dark brown solid (66.3 mg). This material was used in the next step without further purification. MS (ES+) m/z: 486.1 (M+H).
