Sodium Carbonate → HCID 22248033, compound

Participants

Reaction Steps

After dissolving 131 mg of 3-methoxypyrazine-2-carboxaldehyde and 236 mg of (E)-4-[2-[2-(cyclohexylmethyloxy)phenyl]vinyl]piperidine in 3 ml of 1,2-dichloroethane, 0.07 ml of acetic acid and 276 mg of sodium triacetoxyborohydride were added and the mixture was stirred overnight at room temperature. Aqueous sodium carbonate solution was added to the reaction mixture and extraction was performed with ethyl acetate. The extract was washed with water and saturated brine and dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (solvent: n-hexane/ethyl acetate) to obtain the title compound (255 mg, 77% yield).
