70 mg of 1-(piperidin-4-yl)-1H-indole-6-carboxamide and 115 mg of (2-methoxynaphthalen-1-yl)acetaldehyde were dissolved in 2 ml of tetrahydrofuran. Thereafter, 0.03 ml of acetic acid and 91 mg of sodium triacetoxyborohydride were added to the reaction solution, and the obtained mixture was then stirred at room temperature overnight. Thereafter, a saturated sodium bicarbonate aqueous solution was added to the reaction solution, and then extracted 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), so as to obtain 72 mg of the subject compound.
