実験手順
Product of Example 390A (16 mg, 0.027 mmol) in N,N-dimethylformamide (1 mL) was added 1,4-cyclodiene (25.5μl, 0.27 mmol) and palladium black (16 mg). The mixture was heated at 70° C. for 1 day. The mixture was filtered with Celite® and washed with N,N-dimethylformamide. The solution was evaporated under reduced pressure and the residue was chromatographed on silica gel eluting with dichloromethane:methanol (98:2) to give the title compound (6 mg, 44%). 1H NMR (300 MHz, DMSO-d6) δ 0.16 (d, J=4.41 Hz, 2 H) 0.43 (d, J=7.35 Hz, 2 H) 0.99 (m, 1 H) 2.78 (s, br, 2 H) 5.25 (s, 2 H) 6.27 (s, br, 1 H) 7.22 (s, 2 H) 7.31 (m, 1 H) 7.39 (dd, J=9.01, 2.76 Hz, 1 H) 7.49 (d, J=2.57 Hz, 1 H) 7.54 (d, J=8.82 Hz, 1 H) 7.77 (m, 1 H) 7.95 (d, J=8.09 Hz, 1 H) 8.13 (dd, J=8.09 Hz, 1.47 Hz, 1 H) 14.83 (s, br, 1 H).
