Participants

Reaction Steps

In 20 ml of 1,2-dichloroethane was dissolved 1.06 g of ethyl 2-(2-oxoethyl)biphenyl-4-carboxylate, and then 3.95 ml of piperidine, 589 μl of acetic acid, and 1.09 g of sodium triacetoxyborohydride were added thereto, followed by 3 hours of stirring. Water and chloroform were added to the reaction solution, and the organic layer obtained by an operation of separation was dried over anhydrous magnesium sulfate, followed by removal of the solvent by evaporation. The obtained residue was purified by silica gel column chromatography (chloroform:methanol:aqueous ammonia) to obtain 1.3 g of oily ethyl 2-(piperidin-1-ylethyl)biphenyl-4-carboxylate.
