Triethyl phosphonoacetate → HCID 86749011, compound

Participants

Reaction Steps

0.59 g of 55% sodium hydride was suspended in 5 ml of N,N-dimethylformamide in a nitrogen atmosphere, followed by the dropwise addition thereto of 5 ml of a solution of 3.0 g of ethyl diethylphosphonoacetate in N,N-dimethylformamide at room temperature. The obtained mixture was stirred for 10 minutes. 5 ml of a solution of 4.5 g of farnesyl bromide in N,N-dimethylformamide was added to the resulting mixture at room temperature. The obtained mixture was further stirred for one hour, followed by the addition thereto of ice-water. The resulting mixture was extracted with ethyl acetate. The organic layer was washed with a saturated aqueous solution of common salt, dried over anhydrous magnesium sulfate and distilled in a vacuum to remove the solvent. The obtained crude product was purified by silica gel column chromatography (solvent: n-hexane/ethyl acetate) to give 2.6 g of the title compound as a colorless oil.
