実験手順

A solution of 5-(cis-3,5-dimethyl-1-piperazinyl)-2-chloroaniline (D34) (108 mg, 0.45 mmol) in pyridine:dichloromethane (1:1, 4 ml) was treated with 4-bromobenzenesulfonyl chloride (138 mg, 0.54 mmol). The solution was stirred at room temperature for 2 hours, quenched with methanol and concentrated in vacuo. The residue was applied to a SCX cartridge (Varian bond-elute, 5 g) and washed with methanol and 2M ammonia in methanol. The combined basic fractions were concentrated in vacuo and the resulting residue was purified by column chromatography (FlashMaster) (dichloromethane to 5% methanol:dichloromethane) to afford some pure product. The impure fractions were purified further by MDAP, and combined with the above pure product to afford the title product (D35). MS (ES+) m/e 458/460/462 [M+H]+.
