Procedure

To a stirred solution of 3.65 g of 3,4-dihydro-6-methoxy-1-methyl-4-[2-[(1-phenylethyl)amino]ethyl]-2(1H)-quinolinone in 270 ml of refluxing n-butanol was added, incrementally over a period of 1.5 hours, 7.40 g of sodium. The resulting mixture was stirred at reflux until all of the sodium was consumed, and then was cooled, and diluted with water. The aqueous phase was separated and extracted with ethyl acetate. The combined organic phase was washed with water and a saturated aqueous solution of sodium chloride, dried over anhydrous magnesium sulfate, filtered, and concentrated. The concentrate was purified by means of column chromatography on silica gel (elution with triethylamine/methanol/ethyl acetate) to afford 2.04 g (59%) of 1,2,3,4,5,6-hexahydro-8-methoxy-1-methyl-2-(1-phenylethyl)-2,6-methano-1,3-benzodiazocine as an oil.
