PROCEDURE

实验过程

N-Isoamyl-N-(6-hydroxy naphthalene-2-sulfonyl)-D-valine tert-butyl ester (0.33 g, 0.74 mmol) is dissolved in 4 N hydrochloric acid in ethyl acetate (50 mL), and the reaction is allowed to stir at ambient temperature for 16 h. The solvent is removed in vacuo, and the residue is purified by column chromatography (15% hexanes-ethyl acetate) to afford the title compound as a colorless oil (0.26 g, 90% yield). LCMS (m/z): (394.24, M+1; 392.27, M−1).
