Reaction Steps

(S)-Benzyl 4-(difluoromethoxy)-2-(methoxycarbonylamino)butanoate (56 mg, 0.176 mmol) was dissolved in ethyl alcohol (3.5 mL) and under Argon charged with 10% Pd/C (19 mg). The flask was sealed with a rubber septa and the air atmosphere was replaced with H2 from a balloon by applying vacuum and then releasing H2 and repeating this three times. The mixture was stirred for 4 hours at room temperature. Upon completion, the crude mixture was passed through a Elite plug, concentrated down on rotovap and used as-is in the next step. 40 mg (100%).
