Versuchsvorschrift
1.26 g (8.34 mmol) of dioxa-spiro[4.5]decan-8-ol were dissolved in 50 ml of dimethyl acetamide and 695.2 mg (17.4 mmol) of sodium hydride (60%) were added. After stirring 30 minutes at room temperature a solution of 2.0 g (6.95 mmol) of 1-benzyloxy-7-chloro-6-fluoro-isoquinoline (103) in 50 ml of dimethyl acetamide was added and stirring was continued at room temperature. After 1 h the solvent was removed under reduced pressure. The residue was dissolved in dichloromethane and washed with water. The organic layer was dried with magnesium sulfate and evaporated, which gave 3.30 g of the crude product, which was used without further purification. Rt=2.05 min (Method C). Detected mass: 426.5 (M+H+).
