Reaction Steps

Into a flask were introduced 70 g (0.48 mol) of di-n-propylacetic acid, 250 ml of toluene and 30 ml of N,N-dimethylformamide. After this operation, 40 g of 50%-aqueous solution of sodium hydroxide were added. This mixture was heated to 60°-80° C. and 138.7 g (1.5 mol) of epichlorhydrine were introduced. The reaction medium was maintained under stirring for 6 hours at 70°-80° C. and then concentrated in a rotary evaporator. After extraction with ethyl ether, the organic fractions were collected and distilled under 1 mm Hg.
