A mixture of compound 0802 (544 mg, 1.25 mmol) and Inodomethane (0804) (177 mg, 1.25 mmol) and potassium carbonate (1.0 g, 7.25 mmol) in N, N- dimethylformamide (15 mL) was stirred at room temperature for 12 hours. The solvent was removed under reduce pressure and the residue was dissolved in ethyl acetate (50 mL). The organic layer was washed with saturation aqueous NaHCO3 (20 mL) and brine (20 mL). The organic layer was dried over MgSO4 and concentrated to give the title compound 95 as pale yellow solid (500 mg, 89%). m.p.195.8-197.0 0C; LCMS: 449 [M+l]+; 1H NMR (DMSO-J6); delta 1.35 (m, 2H), 1.50 (m, 4H), 1.80 (m, 2H), 1.94 (t, J= 7.2 Hz, 2H), 3.54 (s, 3H), 3.92 (s, 3H), 4.12 (t, J= 6.3 Hz, 2H), 4.19 (s, IH), 7.19 (m, 2H), 7.40 (t, J= 7.8 Hz, IH), 7.80 (s, IH), 7.87 (d, J= 9.6 Hz, IH), 7.97 (s, IH), 8.48 (s, IH), 9.45 (s, IH), 10.92 (s, IH). |
