실험 절차

1.00 g of 4-(4-piperidinomethyl-2-pyridyloxy)-cis-2-butenylamine was dissolved in 20 ml of ethyl acetate. 0.54 ml of triethylamine was added to the solution, and the resulting mixture was cooled in an ice bath. 0.31 ml of 2-chloroacetyl chloride was added, and the mixture was stirred for 1 hour at room temperature. At the end of this time, water was added, and the reaction mixture was extracted with ethyl acetate. The extract was condensed by evaporation under reduced pressure, and the residue was purified by silica gel chromatography, eluted with a 1:19 by volume mixture of methanol and ethyl acetate, to give 0.94 g (yield 73%) of the title compound as an oil.
