실험 절차

To a solution of the obtained (6′-chloro-2-methyl-[3,4′]bipyridinyl-3′-yl)-methyl-carbamic acid tert-butyl ester in dichloromethane is added 0.40 ml trifluoroacetic acid at room temperature. The reaction mixture is stirred at this temperature for about 1.5 h. After addition of an aqueous sodium hydroxide solution, the mixture is extracted with dichloromethane. The combined organic layers are dried and concentrated to give the compound (6′-chloro-2-methyl-[3,4′]bipyridinyl-3′-yl)-methyl-amine of formula IX.
