実験手順
2-(2-tert-butoxycarbonylamino-3-methoxy-propionylamino)-3-naphthalen-2-yl-propionic acid methyl ester, 57, (5.2 g, 12.1 mmol) is dissolved in 4M hydrogen chloride in dioxane (40 mL) and stirred at room temperature for 1 hour. 1,2-Dichloroethane (40 mL) is added. The solution is concentrated in vacuo to afford 4.43 g (quantitative yield) of the desired product.
