Participants

Reaction Steps

(1-Tert-butoxycarbonylaminocyclobutyl)-hydroxyacetic acid (201.5 mg, 0.822 mmol) was stirred with acetic anhydride (95 mL) in pyridine (1.5 mL) for 24 h. The mixture was first concentrated under vacuum, and then diluted with 5 mL EtOAc. The organic solution was washed with 1N HCl (2 mL) followed by saturated aqueous NaCl (2 mL), dried (Na2SO4), and evaporated under vacuum which gave the title compound.
