| Product | 3-Amino-5,6-dichloro-1-[4-(N',N'-diethylureido)-benzenesulfonyl]-1,3-dihydro-3-phenylindol-2-one | HCID 19076454 | — |
Reaction Steps
This compound is prepared according to the procedure described in EXAMPLE 1 from 0.293 g of 3-amino-5,6-dichloro-1,3-dihydro-3-phenylindol-2-one and 0.290 g of 4-(N',N'-diethylureido)benzenesulfonyl chloride. Chromatography on silica using a DCM/AcOEt mixture (85/15; v/v) as the eluent gives the expected product after crystallization from a DCM/iso ether mixture. m=0.26 g. M.p.=119°-121° C.
