Procedure

A solution of 5-(cis-3,5-dimethyl-1-piperazinyl)-2-(methyloxy)aniline (D4) (1.20 g, 5.09 mmol) in dichloromethane (35 ml) was treated with morpholinomethyl-polystyrene HL resin (2.43 g, 4.2 mmol/g loading, 10.21 mmol) and then the 4-bromo-2-chlorobenzenesulfonyl chloride (2.96 g, 10.21 mmol). The resulting solution was stirred at room temperature overnight. The resin and was filtered, washed with methanol, and the solvent evaporated in vacuo. The residue was then passed through an SCX column eluting first with methanol followed by 2M ammonia in methanol. The basic fractions were collectedand solvent evaporated in vacuo to afford a crude product which was purified further by chromatography using a Flashmaster using an elution gradient of 0 to 5% methanol in dichloromethane. The relevant fractions were collected, combined and the solvent evaporated in vacuo to afford the title compound (E104). MS (ES+) m/e 488/490/492 [M+H]+.
