The mixture was stirred at rt for 18 h. The solvent was removed in vacuo and the resulting residue was purified by prep. HPLC. The product was isolated as a white solid (5 mg, 21.1%). LCMS: m/e 644.5 (MH+), 2.80 min (method 3). 1H NMR (400 MHz, MeOD) δ ppm 7.94 (d, J=8.5 Hz, 2H), 7.16-7.34 (m, 2H), 5.32 (dd, J=6.4, 1.6 Hz, 1H), 4.74 (d, J=2.0 Hz, 1H), 4.62 (s, 1H), 3.54 (d, J=13.6 Hz, 1H), 3.04 (d, J=13.8 Hz, 1H), 2.57-2.71 (m, 2H), 2.44-2.57 (m, 2H), 2.17 (dd, J=17.2, 6.4 Hz, 1H), 2.09 (dd, J=13.1, 1.8 Hz, 1H), 1.85 (dd, J=12.2, 3.4 Hz, 2H), 1.65-1.82 (m, 8H), 1.61 (br. s., 2H), 1.53 (d, J=10.5 Hz, 3H), 1.48 (d, J=2.0 Hz, 1H), 1.35-1.45 (m, 3H), 1.24-1.35 (m, 3H), 1.16-1.24 (m, 4H), 1.02-1.16 (m, 8H), 0.99 (s, 3H), 0.95 (s, 3H).
