Versuchsvorschrift

To a mixture of (7-fluoro-6-hydroxy-3-oxo-5,6-dihydro-3H-pyrrolo[1,2,3-de]quinoxalin-6-yl)methyl 4-methylbenzenesulfonate (0.093 g, 0.24 mmol) in ethanol (3 mL) was added 1,1-dimethylethyl (2,3-dihydro[1,4]dioxino[2,3-c]pyridin-7-ylmethyl)4-piperidinylcarbamate (for a synthesis see WO 2004058144 Example 99(h)) (78.5 mg, 0.22 mmol), then sodium carbonate (71.5 mg, 0.68 mmol). The reaction mixture was stirred at room temperature for 16 hours and evaporated to dryness. The residue was placed directly onto the top of a 20 g silica gel column and chromatographed eluting with a 0-100% ethyl acetate in petrol gradient, then with a 0-50% methanol in ethyl acetate gradient to afford the product (70 mg, 52%).
