Procedure
90 mg of chloroformic acid ethyl ester in 1 ml of acetone are added dropwise at 5° C. to 400 mg of 4-{3-[2,6-dichloro-4-(3,3-dichloro-allyloxy)-phenoxy]-propoxy}-N-hydroxy-benzamidine and 127 mg of potassium carbonate in 3 ml of acetone. After 3 hours at 0-5° C., the reaction mixture is poured onto water and extracted with dichloromethane. Concentration of the organic phase and purification over silica gel yield the title compound (compound 1.15).
