実験手順

To a solution of 0.280 g (0.888 mmol) of 1-(5,7-dihydro-4H-furo[2,3-c]pyridin-6-yl)-6-(4-fluorophenyl) hexan-1-one in 20 ml of acetic acid, 0.120 ml (1.33 mmol) of 50% aqueous dimethylamine and 0.108 ml (1.33 mmol) of 37% aqueous formaldehyde were added, followed by stirring at 100° C. for 60 minutes. After the solvent was distilled off under reduced pressure, the residual solution was alkalified with 5% aqueous sodium hydrogen carbonate, and extracted with dichloromethane 2 times. The combined organic layer was washed with water and dried over anhydrous sodium sulfate; the solvent was distilled off under reduced pressure. The resulting crude product was purified by silica gel column chromatography (chloroform/methanol=50/1 to 25/1) to yield the desired product.
