실험 절차

To a stirred solution of (R)-2-tert-butoxycarbonylamino-4-(4-heptyloxy-phenyl)-2-methyl-butyric acid (43 mg, 0.11 mMol) in CH2Cl2 (2 ml) is added trifluoroacetic acid (0.1 ml). The mixture is stirred at RT for 8 hours. After that time, the reaction mixture is concentrated under reduced pressure. Column chromatography eluting with 5%→25% MeOH in CH2Cl2 gives the title compound as a colourless oil.
