3,4-Dichloroaniline → HCID 21414091, compound

Participants

Reaction Steps

A solution of 16 g of N-methylsulfonyl-N-methyl-carbamoyl chloride in 100 ml of tetrahydrofuran was slowly added at less than 10° C. to a mixture of 150 ml of tetrahydrofuran, 9.4 g of triethylamine and 15 g of 3,4-dichloroaniline and after stirring for 3 hours, the insolubles were removed by filtration, and the filtrate was concentrated to dryness under reduced pressure to obtain 16 g of N-methyl-N-methylsulfonyl-N'-(3,4-dichlorophenyl)-urea melting at 140° C. Crystallization from ethanol gave an unchanged melting point.
