실험 절차

To a solution of N-[(R)-1-[3-(1-tert-butoxycarbonyl-4-piperidyl)-(E)-acryloyl]-3-piperidylcarbonyl]-3(R)-(3,4-dimethoxyphenethyl)-β-alanine (1.33 g) in ethyl acetate (10 ml) was added 4N HCl in 1,4-dioxane (5.53 ml) at 0° C., and the reaction mixture was stirred for 3 hours at room temperature. The precipitates were filtered, washed with diethyl ether and resolved in water, neutralized with saturated aqueous NaHCO3, desalted by using the resin of HP-20 eluting with isopropanol:H2O=(1:1), then freeze-dried to give N-[(R)-1-[3-(4-piperidyl)-(E)-acryloyl]-3-piperidylcarbonyl]-3(R)-(3,4-dimethoxyphenethyl)-β-alanine as a white powder (0.88 g, 79.4%).
