Participants

Reaction Steps

N-(2-(5-Chloro-2-fluorophenyl)pyridin-4-yl)-2-(piperidin-4-ylmethyl)-2H-pyrazolo[4,3-b]pyridin-7-amine (20 mg, 0.046 mmol) and N,N-diisopropylethylamine (7.97 μl, 0.046 mmol) were combined in dichloromethane (1.5 mL) followed by ethyl isocyanate (3.62 μl, 0.046 mmol). The reaction was then stirred at room temperature over night. The solvent was then evaporated to give a residue which was partitioned between EtOAc and 1N NaOH. The organic layer was washed with water and then brine, dried over Na2SO4, filtered, concentrated, and evaporated in-vacuo to give the title compound as a light yellow solid. MS [M+H] found 507.0.
