実験手順

Trifluoroacetic acid (17.4 g) was added in one portion to a solution of 5,6,7,8-tetrahydro-5-methyl-2-(phenylmethoxy)-quinolin-5-ol (41 g), phenylmethoxyamine (47 g), and toluene (770 ml) at room temperature. The solution was stirred at room temperature for 24 hrs, and then quenched with concentrated ammonium hydroxide solution. The layers were separated and the aqueous phase was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over potassium carbonate, filtered, and the filtrate was concentrated. Purification by high performance liquid chromatography (silica gel, elution with ethyl acetate-hexanes) gave 44.2 g (77%) of 5,6,7,8-tetrahydro-5-methyl-N,2-bis(phenylmethoxy)-5-quinolinamine.
