Potassium Acetate → HCID 53931630, compound

Participants

Reaction Steps

3 g (10.5 mmol) of methyl 2-(p-bromomethylphenyl)-3-methoxyacrylate (prepared similarly to EP 226 917), 1.1 g (11.2 mmol) of potassium acetate and 50 mg of potassium iodide in 70 ml of N-methylpyrrolidone are stirred for 3 hours at 70°-80° C. The reaction mixture is diluted with water and extracted three times with ether. The combined ether phases are washed with water, dried over MgSO4 and evaporated down. Purification of the residue by column chromatography gives 2.3 g (8.7 mmol, 83%) of the title compound as colorless crystals (mp.= 69°-70° C.).
