実験手順

To a solution of (S)-tert-butyl 2-(2-(tert-butoxycarbonylamino)butoxy)acetate (1 eq, from the previous step) in DCM (0.4 M) at room temperature was added a solution of 4 M HCl in dioxane (10 eq). The reaction was stirred for 2 hours, at which time more 4 M HCl in dioxane (3 eq) was added and stirred for 1 hour. The reaction mixture was concentrated en vaccuo to give the product as an oil. The material was carried onto the next step without further purification.
