Reaction Steps

To a solution of 4-fluoro-2-methoxyphenol (569 mg, 4.0 mmol) and pyridine (0.56 mL, 7.0 mmol) in CH2Cl2 (8.0 mL) at 0° C. was added acetyl chloride (0.33 mL, 4.6 mmol). The mixture was stirred at rt for 2.0 h and then diluted with EtOAc and washed with 4.0 N HCl. The organic layer was washed with brine and dried over Na2SO4. After evaporation of the solvent, 64A (680 mg, 92% yield) was obtained as a solid used in the next step without further purification. 1H NMR (400 MHz, CDCl3) δ ppm 2.29 (s, 3H) 3.79 (s, 3H) 6.62 (m, 1H) 6.68 (dd, J=10.33, 2.86 Hz, 1H) 6.95 (dd, J=8.79, 5.71 Hz, 1H).
