Procedure

To alcohol 25 (900 mg, 3.23 mmol) and pyridine (0.8 mL, 10 mmol) in dry CH2Cl2 (15 mL) at 0° C. was added acetyl chloride (0.3 mL, 4.2 mmol). The resulting mixture was stirred for 2 hours, the diluted with CH2Cl2 (10 mL) and 5% HCl (10 mL). The mixture was transferred to a separatory funnel and the organic layer washed with H2O and brine. The organic layer was dried (Na2SO4), solids filtered and the solvent removed in vacuo to provide the desired acetate 26 as a yellow waxy solid (1.04 g, 100%).1H NMR (CDCl3; 400 MHz): δ: 8.72 (s, 1H), 8.30 (d, 1H, J=1.7 Hz), 7.98 (m, 2H), 7.49 (m, 2H), 7.30 (m, 1H), 7.25 (m, 2H), 6.84 (d, 1H, J=16.0 Hz), 6.46 (m, 1H), 4.79 (dd, 2H, J=6.2 Hz, 1.2 Hz), 2.11 (s, 3H).
