Reaction Steps
In a 500 ml flask with a 40 cm Vigreux column, there are put 32 g (0.15 mole) of methyl 2-methoxy-4-hydroxy-5-chlorobenzoate, 120 ml of xylene and 23 g of levo 1-ethyl-2-aminomethylpyrrolidine. It is heated gently. A solution is obtained. The methyl alcohol formed in the form of a methanol-xylene azeotrope is distilled at 60°-62° C in about an hour. At the end of the reaction, 10 ml of xylene is distilled at 135° C. In the distillate, 5 ml of alcohol are recuperated for 6 ml theoretical.
