실험 절차
1 mmol of 6′-Chloro-2,3,5,6-tetrahydro-[1,2′]bipyrazinyl-4-carboxylic acid tert-butyl ester [example 4.9(a)] was dissolved in a solution of sodium methanolate (prepared by dissolving 1 mmol of sodium in 10 ml of methanol). The mixture was heated overnight to 70°, concentrated and the product purified by chromatography (SiO2; dichloromethane/methanol 99:1) to yield the title compound as a colorless foam. MS (m/e): 295.3 (MH+, 100%)
