Procedure

3-Cyclobutyl-7-(piperidin-4-yloxy)-2,3,4,5-tetrahydro-1H-benzo[d]azepine (E6) (150 mg, 0.5 mmol) was stirred in dichloromethane (5 ml) with diethylaminomethyl polystyrene (3.2 mmol/g, 625 mg, 2 mmol). Methane sulfonyl chloride (43 μL, 0.55 mmol) was added and the mixture stirred at room temperature for 16 hours. The resin was filtered, washed with dichloromethane and the filtrate concentrated in vacuo. The residue was purified by column chromatography eluting with a mixture of 0.880 ammonia:ethanol:dichloromethane (1:9:90) to afford the title product (E72); MS (ES+) m/e 379 [M+H]+.
