To a solution of 404 (0.295 g, 0.601 mmol) in pyridine (3.0 mL) under nitrogen was added acetic anhydride (1.59 mL, 16.84 mmol), and the mixture was stirred for 19 h at room temperature. The solvent was evaporated and the residue obtained was evaporated twice with toluene and triturated with a mixture of Et2O and hexanes.
