实验步骤: A solution of 5-(cis-3,5-dimethyl-1-piperazinyl)-2-(methyloxy)aniline (D4) (400 mg,1.70 mmol) in dichloromethane (15 ml) was treated with morpholinomethyl-polystyrene HL resin (1.00 g, 3.4 mmol/g loading) followed by 4-bromo-3-fluorobenzenesulfonyl chloride (0.50 ml, 930 mg, 3.40 mmol). The resulting solution was stirred at room temperature for overnight (20 hours). The reaction mixture and was then filtered, washed with methanol, and the solvent evaporated in vacuo. The residue was applied to an SCX column eluting first with methanol and then 2M ammonia in methanol. The fractions containing product were collected, combined and evaporated in vacuo to afford a crude product which was dry loaded onto a column and purified further by chromatography using a Flashmaster with an eluting gradient of 0 to 5% methanol in dichloromethane over 40 mins. Fractions containing product were combined and evaporated in vacuo to afford the title compound (E105). MS (ES+) m/e 472/474 [M+H]+. The reaction mixture and was then filtered washed with methanol the solvent evaporated in vacuo eluting first with methanol The fractions containing product were collected evaporated in vacuo to afford a crude product which was dry purified further by chromatography over 40 mins Fractions containing product evaporated in vacuo

实验步骤: The title compound was prepared according to the general procedures for the synthesis of N-Aryl-benzenesulfonamides previously described using (2-amino-5-chloro-phenyl)-(pyridin-3-yl)-methanone 2 g (8.7 mmol) and 4-bromo-3-fluoro-benzenesulfonyl chloride 2.35 g (8.77 mmol) in 15 ml pyridine. Purification with silica chromatography eluted with dichlorometane:10-ethyl acetate gave a yellow powder. Purification with silica chromatography eluted with dichlorometane

实验步骤: The title compound was prepared according to the general procedures for the synthesis of N-Aryl-benzenesulfonamides previously described using (2-amino-5-chloro-phenyl)-(6-methyl-pyridin-3-yl)-methanone 2.4 g (8.77 mmol) and 4-bromo-3-fluoro-benzenesulfonyl chloride 2.16 g (8.77 mmol) stirred in 14 ml pyridine. Purification on silica gel with flash column chromatography gave a light orange solid. Purification on silica gel with flash column chromatography gave a light orange solid
