methyl 2-(2-chloro-6-fluorophenyl)acetate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A mixture of methyl (2-chloro-6-fluorophenyl)acetate (5.20 g) and methyl formate (31.4 ml) in dry DMF (40 ml) was added dropwise to a stirred suspension of sodium hydride (1.23 g) in dry DMF (40 ml) at a temperature between 0 and 5° C. Vigorous evolution of gas was observed. The reaction mixture was stirred at room temperature for 3.5 hours, then poured into a mixture of ice and aqueous sodium carbonate, and washed with ether. The resulting aqueous mixture was acidified with concentrated hydrochloric acid and extracted with ether. The extracts were washed with water, dried and concentrated to give methyl 2-(2-chloro-6-fluorophenyl)-3-hydroxypropenoate (3.44 g) as a white solid. washed with ether extracted with ether The extracts were washed with water dried concentrated
