A mixture of 499.2 mg (3.35 mmol) of 1,2,3,4-tetrahydro-8-quinolinol (see Example 7A), 425 mg (5.05 mmol, 1.5 eq.) of sodium bicarbonate, and 780 μl (3.69 mmol, 1.1 eq.) of 98% 1-bromodecane in 10 ml of hexamethylphosphoric triamide under argon was stirred for three hours at room temperature, followed by 44 hours at 50° C. The reaction was diluted with 80 ml of 1:1 ether:petroleum ether and the organic layer was washed with five 40 ml portions of water and 40 ml of brine, dried over sodium sulfate and evaporated to yield 1.04 g of a brown oil. Purification by flash chromatography on 110 g of silica, eluted with 5:95 ethyl acetate:petroleum ether afforded 624.4 mg of the title compound as a colorless oil.
