Procedure

A mixture of methanesulfonyl chloride (0.38 mL) in methylene chloride (20 mL) is added dropwise to a mixture of 9-(2-hydroxyethyl)-2,4-di-1-pyrrolidinyl-9H-pyrimido[4,5-b]indole (VIII, EXAMPLE3, 1.05 g) and triethylamine (0.5 mL) in methylene chloride (25 mL). After a few minutes, the reaction mixture is diluted with water and extracted with methylene chloride. The organic layer is dried (sodium sulfate) and concentrated, to give the title compound.
