Sodium hydride → HCID 57419607, compound

Participants

Reaction Steps

To a stirred solution of tert-butyl 3-(hydroxy(phenyl)methyl)pyrrolidine-1-carboxylate (205 mg, 0.74 mmol) and 4-methoxybutyl iodide (750 mg, 3.5 mmol) in dry THF (5 mL) under N2 was added 60& NaH in oil (0.14 g, 3.5 mmol). H2 evolution occurred. The mixture was heated at reflux for 8 h. The mixture was cooled, diluted with ether (90 mL), and washed with water (25 mL) and brine (25 mL), and dried over MgSO4. Removal of the solvent left an oil which was purified by flash chromatography on a 12-g silica cartridge eluted with a 0 to 100% EtOAc in hexanes gradient to afford tert-butyl 3-((4-methoxybutoxy)(phenyl)methyl)pyrrolidine-1-carboxylate (47 mg, 17%) as an oil.
