2-Pyrrolidone → HCID 86679117, compound

Participants

Reaction Steps

To a suspension of sodium hydride (60% in mineral oil, 0.044 g, 1.09 mmol) in DMF (2 mL) was added pyrrolidin-2-one (0.081 g, 0.945 mmol) and the reaction mixture was stirred at room temperature for 20 min. Then, 3-bromo-5-chloromethyl-pyridine (0.15 g, 0.727 mmol) was added and the resulting suspension was heated at 60° C. over night. The mixture was quenched with water (2 mL) and extracted with EtOAc (2×10 mL). Combined organics were dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by silica gel flash chromatography eluting with a 0 to 5% MeOH-DCM gradient to give the title compound (0.217 g, 87%) as a white solid. MS: 251.1, 257.1 (M+H+).
