3-Furancarboxamide,tetrahydro-N-methoxy-N-methyl-(9CI) → HCID 21702750, compound

Participants

Reaction Steps

To a stirred solution of N-methoxy-N-methyltetrahydrofuran-3-carboxamide (4.1 g) in THF (40 ml) was added ethylmagnesium bromide (3 M in ether, 13.0 ml) at 0° C. The reaction mixture was then slowly warmed to room temperature and stirred for 4 h. The reaction mixture was quenched with saturated 1 M HCl (10 ml), and extracted with EtOAc. The extract was washed with brine, dried over Na2SO4 and concentrated in vacuo. The mixture was purified by silica gel column chromatography (hexane/EtOAc) to give the title compound (3.0 g) as a pale yellow liquid.
