Procedure: Using a similar procedure to that described in Example 32, except starting from E,E-4-[3,6-di-(3oxo-3-pyrrolidino-1-propenyl)indol-1-ylmethyl]- 3-methoxybenzoic acid, and using 2-chlorobenzenesulfonamide, title compound was obtained (87%) as powder, mp 291°-293°.

Conditions: temp:70.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2-Chlorobenzenesulphonyl chloride (58 g) in either (60 ml) was added dropwise with stirring to concentrated ammonia solution (575 ml). When addition was complete, the mixture was stirred and heated at 70° C. for 1 hour. The mixture was then cooled and the solid filtered off, washed with water, and dried to give the required 2-chlorobenzenesulphonamide (39 g) with a melting point of 186° C. When addition The mixture was then cooled the solid filtered off washed with water dried
