반응 단계
A solution of 24 g of bentazone (IIa) in 216 g of 1,2-dichloroethane was treated with 22.5 g of a 20% strength aqueous solution of dimethylamine with stirring at 30°-50° C. After addition was complete, the aqueous phase was separated off at 50°-60° C. and evaporated to dryness under reduced pressure and at 50°-60° C. 28 g of bentazone-dimethylammonium (m.p. 145°-147° C.; purity >99% according to HPLC analysis for bentazone and titration for dimethylammonium) were obtained.
