HCID 68534115[5-(4-Isopropyl-piperazine-1-carbonyl)-1H-indol-2-yl]-[4-(propane-2-sulfonyl)-piperazin-1-yl]-methanoneYield 87%

Procedure

The title compound was synthesized in analogy to example 1, from 5-(4-isopropyl-piperazine-1-carbonyl)-1H-indole-2-carboxylic acid hydrochloride (example 1, intermediate b) and 1-(1-methylethylsulfonyl)piperazine (prepared in analogy to WO2003064413 using isopropylsulfonyl chloride and tert-butyl 1-piperazinecarboxylate) to afford the desired product as a light-brown solid (87%). MS (ISP): 490.3 (M+H)+.
