Sodium Bicarbonate → 1-{1-[2-(6-Methoxy-2-oxo-1,2,3,4-tetrahydroquinolin-7-yl)ethyl]piperidin-4-yl}-1H-indole-6-carboxamide

Participants

Reaction Steps

100 mg of 1-(piperidin-4-yl)-1H-indole-6-carboxamide and 87 mg of (6-methoxy-2-oxo-1,2,3,4-tetrahydroquinolin-7-yl)acetaldehyde were suspended in 5 ml of methylene chloride. Thereafter, 0.05 ml of acetic acid and 0.13 g of sodium triacetoxyborohydride were added to the reaction solution, and the obtained mixture was stirred at room temperature overnight. Thereafter, a saturated sodium bicarbonate aqueous solution was added to the reaction solution, 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 (chloroform-methanol) and by NH silica gel column chromatography (chloroform-methanol), and then reprecipitated from ethyl acetate, so as to obtain 18 mg of the subject compound.
