Reaction Steps

A mixture of 10 g of N-methyl-hydroxylamine hydrochloride in 100 ml of chloroform was stirred while 18 ml of triethylamine were added at 0° C. Then, 20 g of 3,5-dichlorophenyl isocyanate in 30 ml of chloroform were added to the mixture at 10° to 15° C and the mixture was stirred for 5 hours at 20° C and was then distilled to dryness under reduced pressure. The residue was taken up in water and dried to obtain 22 g of N-methyl-N-hydroxy-N'-(3,5-dichlorophenyl)-urea melting at 131°-132° C.
