実験手順

To a cooled (0° C.) solution of (S)-2-tert-butoxycarbonylamino-4-dimethylaminobutyric acid methyl ester (23.4 g, 90 mmol) in dioxane (100 mL) was added drop-wise HCl (225 mL, 4M in dioxane). The mixture was warmed to room temperature and stirred for 3 hours. The solid was filtered, washed with ether (3×100 mL), and dried under high vacuum to afford 20.2 g of product (96% yield).
