Procedure
The title compound was synthesized as described for Example 178 in 96% yield, starting from 2-amino-5-methylbenzenesulfonamide and (E)-2-(4-bromophenyl)ethenesulfonyl chloride (US20040186134 A1). Purification by column chromatography using a gradient of 10-50% ethyl acetate in heptane as the eluent.
