Reaction Steps

Benzotriazol-1-yl-oxy-tris(dimethylamino)phosphonium hexafluorophosphate (BOP reagent) (1.22 g, 0.00275 g) was added to a solution of 5-chloro-3-(3,5-dimethylphenyl-sulfonyl)indole-2-carboxylic acid (12) (1.00 g, 0.00275 mol), N-methylpiperazine (0.55 g, 0.0055 mol), triethylamine (0.55 g, 0.0055 mol) in anhydrous DMF (50 mL). Reaction was stirred at room temperature for 72 hours, then diluted with water and extracted with ethyl acetate. Organic extracts were washed with brine, dried and the solvent evaporated to give 1.20 g (98%) of pure title compound, mp 281-283° C. (from aqueous ethanol).
