The reaction was heated to 60C for 16 h under a nitrogen atmosphere. After cooling the reaction to room temperature, the mixture was concentrated in vacuo. DCM (50 mL) was added and the mixture was washedwith water (30 mL x 3) and brine (30 mL). The organic layer was dried over anhydrousNa2SO4, filtered and concentrated in vacuo. The crude residue was purified by reverse phasechromatography (acetonitrile 40-70% \/ 0.05% NH4OH in water) to give the title compound(11 mg, 11%) as a white solid. 111 NMR (400 MHz, DM80-cl6) 6 7.73 (d, Jr 2.0 Hz, IH),7.44 (t,J 55.6 Hz, IH), 7.32 (s, lH), 6.86 (s, 111), 6.55 (d,Jr 4.0 Hz, IH), 6.46 (s, 1H),4.33 -4.23 (m, IH), 4.02 (s, 211), 3.95 &#8211; 3.93 (m, 211), 3.86 (s, 311), 3.61 &#8211; 3.58 (m, 414), 3.48-3.42 (m, 211), 2.89-2.71 (m, 4H), 2.53 (d,J= 4,4 Hz, 3H), 2.01 &#8211; 1.93 (m, 4H), 1.82- 1.80 (m, 211).
