Hydrogen chloride-ethyl acetate → HCID 66906426, compound

Participants

Reaction Steps

To a solution of the crude 6-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-(2-fluorophenyl)piperidin-1-yl]-5-chloronicotinic acid obtained in the aforementioned reaction in 2.0 mL of ethyl acetate was added 1.00 mL of a 4 M hydrogen chloride/ethyl acetate solution, followed by stirring at room temperature for 2 hours. The reaction mixture was concentrated under reduced pressure, and the residue was purified by reverse phase silica gel column chromatography (acetonitrile-0.01 M hydrochloric acid) to obtain 56 mg of 5-chloro-6-[3-(2-fluorophenyl)-4-({[(1R)-1-(1-naphthyl)ethyl]amino}methyl)piperidin-1-yl]nicotinic acid hydrochloride as a white solid.
