| Reactant | 1-(Bromomethyl)-2,3-difluoro-benzene | HCID 517984 | — |
| Reactant | Ethyl acetoacetatesodium salt | HCID 87089461 | — |
| Solvent | Tetrahydrofuran | HCID 8028 | — |
| Product | Ethyl 2-(2,3-difluorobenzyl)-3-oxobutyrate | HCID 57460769 | 79% |
Reaction Steps
A solution of 1-(bromomethyl)-2,3-difluorobenzene (1.6 g) and ethyl acetoacetate sodium salt (2.36 g) in tetrahydrofuran (20 mL) was stirred for 12 hr. The insoluble material was filtered off, and the filtrate was concentrated. The residue was purified by silica gel column chromatography to give the title compound (1.56 g, 79%) as a colorless viscous oil.
