Versuchsvorschrift

To a 1 L round-bottomed flask equipped with condenser and N2 inlet were added 10.0 g (44 mmol) 4-bromo-5,6,7,8-tetrahydro-naphthalen-1-ol (Example 37A), 19 g (130 mmol) 2-dimethylaminoethyl chloride hydrochloride, 30.3 g (220 mmol) powdered potassium carbonate, and 600 mL acetonitrile. The reaction was refluxed 60 hours, followed by an additional portion of the chloride and continued refluxing for 24 hours. The reaction was cooled, filtered and concentrated. The residue was chromatographed on silica gel using methanol/methylene chloride as eluant to afford 8.55 g (65%) of a light brown oil.
