Reaction Conditions

Reaction Steps

To a stirred mixture of benzyl 3-isobutyryl-2-propylindole-6-carboxylate (207 mg) and diisopropylethylamine (295 mg) in dichloromethane (6 ml) were added 2-chlorobenzoyl chloride (299 mg) and 4-dimethylaminopyridine (12 mg) at 0° C. The reaction mixture was refluxed for 15 hours. The reaction mixture was cooled to 20° C. and washed with 1N hydrochloric acid, water, saturated sodium bicarbonate, water and brine. The organic phase was dried over sodium sulfate and evaporated in vacuo. The residue was chromatographed or silica gel eluting with a mixture of ethyl acetate and hexane (1:10) to give benzyl 1-(2-chlorobenzoyl)-3-isobutyryl-2-propylindole-6-carboxylate (330 mg) as yellow crystals.
