実験手順

129 mg of 3-amino-4-(2,2-dimethoxyethyl)benzamide and 87 mg of 1-(2-(6-methoxy-1-methyl-1,2,3,4-tetrahydroquinolin-7-yl)ethyl)piperidin-4-one were dissolved in 4 ml of acetic acid. Thereafter, 0.49 g of sodium sulfate was added to the reaction solution, and the obtained mixture was then stirred at room temperature for 1 hour. Thereafter, 0.12 g of sodium triacetoxyborohydride was added to the reaction solution, and the obtained mixture was then stirred at room temperature for 1 hour. Thereafter, 4 ml of water was further added to the reaction solution, and the obtained mixture was then stirred at 100° C. for 2 hours. The reaction solution was cooled to a room temperature, followed by concentration under a reduced pressure. A saturated sodium bicarbonate aqueous solution was added to the residue, followed by extraction with chloroform. The extract was dried over magnesium sulfate and then concentrated under a reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate-methanol) and by NH silica gel column chromatography (ethyl acetate), so as to obtain 70 mg of the subject compound.
