Reaction Steps

6-(2-Methoxy-4-methoxymethoxyphenyl)-5-(2-methoxyphenylaminomethyl)-2,2,4-trimethyl-1,2-dihydroquinoline (Reference Compound No. 3-1, 181 mg, 0.381 mmol) was dissolved in 1,4-dioxane (3 mL), 4N HCl/1,4-dioxane solution (1 mL) was added thereto, and then the mixture was stirred at room temperature for 2.5 hours. The mixture was diluted with ethyl acetate (30 mL), washed with saturated aqueous sodium hydrogen carbonate solution (30 mL), water (30 mL) and saturated brine (30 mL) successively, dried over anhydrous magnesium sulfate, and then the solvent was removed under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled reference compound (101 mg) as a pale orange solid. (Yield 62%)
