Reaction Steps

6-(2-Methoxy-5-phenylacetylphenyl)-5-(4-methylbenzoyloxymethyl)-2,2,4-trimethyl-1,2-dihydroquinoline (Compound No. 22, 34.0 mg. 0.0623 mmol) was dissolved in tetrahydrofuran (0.5 mL)—methanol (0.5 mL), and sodium borohydride (6.8 mg, 0.180 mmol) was added thereto, and then the reaction mixture was stirred at room temperature for 45 minutes. 1N aqueous HCl solution (0.5 mL) and ethyl acetate (50 mL) were added to the reaction mixture, the whole was washed with water (50 mL, twice) and saturated brine (50 mL) successively, dried over anhydrous magnesium sulfate, and then the solvent was removed under reduced pressure. The residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled compound (31.8 mg) as a colorless amorphous product (yield: 93%)
