実験手順

A suspension of the product of Example 1F (617 mg, 1.95 mmol) and the product of Example 2D (542 mg, 1.95 mmol) in toluene (20 mL) was stirred at reflux for 18 hours and concentrated in vacuo to afford the title compound (1.1 g, 100%). 1H NMR (300 MHz, CDCl3): δ 17.85 (d, J=12.13 Hz, 1 H), 12.49 (s, 1 H), 12.35 (s, 1 H), 8.32 (d, J=6.62 Hz, 1 H), 8.18 (m, 1 H), 7.98 (d, J=9.19 Hz, 1 H), 7.66 (m, 2 H), 7.42 (m, 3 H), 7.27 (m, 4 H), 5.49 (s, 1 H), 5.37 (s, 1 H), 5.07 (d, J=30.89 Hz, 2 H), 2.31 (m, 2 H), 1.86 (m, 2 H), 0.94 (m, 2 H), 0.72 (m, 8 H).
