The mixture was stirred for 16 h and quenched extracted as in Example 1(d). The solvent was distilled off to afford the crude residue which was purified by column chromatography to give the product in 51% yield (25 mg). 1H NMR (300 MHz, DMSO): δ 10.6 (s, 1H) 8.99 (d, 2H), 8.88 (d, 1H), 8.62 (d, 1H), 8.31 (d, 1H), 7.92 (d, 1H), 7.76-7.71 (m, 2H), 7.47-7.40 (m, 1H), 7.29-7.24 (m, 1H), 4.33-4.30 (d, 2H), 3.64-3.62 (m, 2H), 3.12-3.09 (m, 2H), 1.87-1.83 (m, 1H), 0.63-0.61 (t, 2H), 0.49-0.48 (t, 2H); LC-MS (ESI): Calculated mass: 511.5; Observed mass: 511.8 [M+H]+ (rt: 1.63 min).
