Reaktionsschritte

2-(N,N-Dimethylamino)methyl-6-hydroxytetralin (5.0 g; obtained in Reference Example 16) was dissolved in DMF (130 ml), to which was added 60% oily sodium hydride (1.46 g) at 0° C. The reaction mixture was warmed to room temperature, and stirred for 1 hour. This was again cooled to 0° C., to which was added a DMF solution (20 ml) of 4-bromobenzyl bromide (10.0 g). The reaction mixture was stirred at room temperature for 2 hours, and water was added thereto, which was then extracted with ethyl acetate. The organic layer was washed with water and a saturated aqueous sodium chloride solution, then dried, and concentrated. The residue was purified by alumina column chromatography (eluent: ethyl acetate/hexane=1/10) to obtain the entitled compound (3.4 g).
