실험 절차
A solution of 1.0 g (4.44 mmol) (R)-1-acryloyl-pyrrolidine-2-carboxylic acid tert-butyl ester and 0.33 ml (2.22 mmol) veratrylamine in 25 ml acetonitrile was stirred for 16 h at 80° C. Concentration in vacuo abash chromatography (gradient: 0-10% MeOH in EtOAc) afforded 150 mg (10%) of the title compound as a light brown oil. MS m/e (%): 618 (M+H+, 100).
