실험 절차
6-(2,4-Dichloro-benzylcarbamoyl)-2,6-diaza-spiro[3.3]heptane-2-carboxylic acid tert-butyl ester (20 mg, 50 μmol) and trifluoroacetic acid (740 mg, 6.49 mmol) were dissolved in dichloromethane (2 mL) and the reaction mixture was stirred for 30 min at ambient temperature. Concentration of the reaction mixture in vacuo afforded the title compound which was used without further purification.
