Reaction Steps

1.0 g of ethyl (E)-3-[1-(1-methylethy)-1,2,3,4-tetrahydroquinolin-6-yl]-2-butenoate prepared in Example 1 was dissolved in 20 ml of tetrahydrofuran. The obtained solution was cooled to −70° C., followed by the gradual addition of 7.0 ml (10.5 mmol) of a 1.5 M solution of diisobutylaluminum hydride in toluene. The obtained mixture was stirred for 2 hours, followed by the addition of an aqueous solution of ammonium chloride. The obtained mixture was extracted with ethyl acetate. The organic phase was washed with a saturated aqueous solution of common salt, dried over anhydrous magnesium sulfate and concentrated in a vacuum to give 650 mg of the title compound as a colorless oil.
