Versuchsvorschrift

To a mixture of (1,1-dioxo-thiomorpholin-4-yl)-[5-(1-isopropyl-piperidin-4-yloxy)-1H-indol-2-yl]-methanone (Example 2, 100 mg, 1.0 eq.) and isopropyl-methanesulfonate (67 mg, 2.0 eq.) in dimethylformamide (4 mL) was added cesium carbonate (156 mg, 2.0 eq.). The solution was stirred 22 h at 95° C. The reaction mixture was concentrated in vacuo and the residue partitioned between water and methyl-tert-butylether. The aqueous layer was extracted with methyl-tert-butylether. The combined organic layer was washed with brine, dried over sodium sulfate, filtered, concentrated in vacuo and then purified on silica, eluting with cyclohexane/ethyl acetate. One fraction was isolated and dried in vacuo, to yield 52 mg (47%) of the desired product as off-white solid. MS (m/e): 462.5 (MH+, 100%)
