Sodium Bicarbonate → N1-(3-Fluorobenzyl)-2-[1-[2-(2-methoxy-3-pyridyl)ethyl]-2-piperidyl]acetamide

Participants

Reaction Steps

200 mg of 2-(2-methoxy-3-pyridyl)acetaldehyde, 400 mg of N1-(3-fluorobenzyl)-2-(2-piperidyl)acetamide, 440 mg of sodium triacetoxyborohydride and 0.12 ml of acetic acid were suspended in THF, followed by stirring at room temperature for 1 hour. An aqueous sodium bicarbonate was added thereto, and the mixture was extracted with ethyl acetate. The extract was dried over sodium sulfate. After filtering off the drying agent, the solvent was evaporated. The residue was purified by silica gel column chromatography (ethyl acetate:methanol=8:1, subsequently 4:1), to give 370 mg of a yellow oil.
