Sodium hydride → 2-(4-Chloro-3-cyclopropyl-5-phenyl-pyrazolo[3,4-c]pyridazin-1-yl)-1-pyrrolidin-1-yl-ethanone

Participants

Reaction Steps

Sodium hydride (60% in mineral oil, 18 mg, 0.44 mmol) was added to a solution of 4-chloro-3-cyclopropyl-5-phenyl-1H-pyrazolo[3,4-c]pyridazine (100 mg, 0.37 mmol) and 2-chloro-1-(pyrrolidin-1-yl)ethanone (82 mg, 0.55 mmol) in dry DMF (3 mL) at room temperature for 16 h. The reaction mixture was diluted with ethyl acetate and water. The organic layer was washed with water, dried (MgSO4), filtered and concentrated in vacuo. The residue was purified by column chromatography (silica gel, CH2Cl2/diethyl ether 8:2) to provide Compound Iee as a solid (65 mg).
