Participants

Reaction Steps

A solution of 15 g of 5-(2,6-dichloro-4-trifluoromethyl- phenoxy)-2-nitro-α-phenoxypropionyl chloride in 30 ml of toluene was added dropwise to a solution of 3.7 g of ethyl hydroxyacetate and 4 g of triethylamine in 70 ml of toluene cooled to 0° to 5° C. The reaction mixture was stirred at room temperature overnight, diluted with 300 ml of toluene, washed to neutrality, dried, filtered and evaporated. 13.5 g ethoxycarbonylmethyl 5-(2,6-dicloro-4-trifluoromethyl-phenoxy)-2nitro-α- phenoxy-propionate were initially obtained in the form of a yellowish oil which then crystallised. Melting point: 75° to 76° C. The yield of pure substance was calculated to be 70.5% of theory.
