Procedure

Compound 275 (750 mg, 1 eq.) in trifluoroacetic acid (5 mL) was stirred at room temperature for 10 min. Then, the acid was evaporated, ethyl acetate added and concentrated again in diminished pressure. The residue was triturated in diethyl ether to give the compound 276 as a white solid in quantitative yield. 1H NMR (CDCl3, 400 MHz) δ (ppm) 2.59 (d, J=0.81 Hz, 3H), 4.10 (s, 3H), 7.19 (d, J=9.25 Hz, 1H), 7.22 (d, J=0.81 Hz, 1H), 7.25 (s, 1H), 8.36 (d, J=9.25 Hz, 1H), 10.51 (br s, 1H); MS (ESI, EI+): m/z=306.93 (MH+).
