[D 7 ]bentazone (95 atom% D) was synthesized from methyl antranilate and [D 7 ]isopropylsulfamoyl chloride. [D 7 ]isopropylsulfamoyl chloride was prepared by treatment of [D 7 ]isopropyl amine with chlorosulfonic acid and phosphorous pentachloride. The overall yield from [D 7 ]isopropyl amine was 7%.
