실험 절차

F2 was dissolved in DCM (0.35M) and di tert-butyl carbonate (1.3 eq) and pyridine (1.0 eq) added at RT. After 30 minutes ammonium bicarbonate (1.3 eq) was added and stirring continued for 20 hours. 1M HCl (5 mL/g) was added and the phases separated, the organic layer was washed twice with water and concentrated to a low volume. The crude compound (F3) was filtered through a pad of silica and then crystallised from methyl tert-butyl ether.
