N-[4-(肼磺酰基)苯基]乙酰胺 | 4-acetamidobenzenesulfonylhydrazine | 3989-50-2 | C8H11N3O3S | 229.26 |
An efficient method for the preparation of sulfonamidourea using triphosgene in organic solvents is reported.Sulfonylhydrazides and acetylsulfanilylhydrazide were transformed into the corresponding intermediates using triphosgene in 1,4-dioxane/water or tetrahydrofuran as solvents.These intermediates were converted in situ into symmetrical and unsymmetrical sulfonamidoureas in high yields and shorter periods of time related to previous methods.
