実験手順

A solution of Example 24G (0.044 g, 0.122 mmol) in CH2Cl2 (2 mL) was treated with triethyl amine (0.051 mL, 0.366 mmol) followed by acetyl chloride (0.0173 mL, 0.244 mmol). The reaction was stirred at 25° C. for 1 hour and was concentrated under reduced pressure on a rotary evaporator. The residual white solids (0.075 g) were purified by flash chromatography on silica gel eluting with a solvent gradient of 30% to 50% ethyl acetate in hexanes to provide 0.035 g (71%) of the title compound as a white solid. 1H NMR (300 MHz, DMSO-d6) δ ppm 8.49 (d, J=8.09 Hz, 1H) 7.49 (d, J=3.68 Hz, 1H) 7.39 (d, J=9.19 Hz, 2H) 7.02 (d, J=9.19 Hz, 2H) 6.99 (dd, J=3.68, 0.74 Hz, 1H) 5.09-5.20 (m, 1 H) 4.63 (heptet, J=5.88 Hz, 1H) 1.85 (s, 3H) 1.45 (d, J=6.99 Hz, 3H) 1.28 (d, J=5.88 Hz, 6H); MS (ESI) m/z 404 (M+H)+.
