Versuchsvorschrift

To a solution of 318 (470 mg, 1.01 mmol) and diethyl malonate (0.17 mL, 1.11 mmol) in anhydrous tetrahydrofuran (10 mL) under nitrogen was added sodium hydride (60% in oil, 89 mg, 2.22 mmol). The mixture was heated to reflux for 2 h, cooled, diluted with EtOAc and water and acidified to pH 3 using a 1N HCl solution. The organic layer was separated and the aqueous layer extracted twice with EtOAc. The extracts were combined, dried over sodium sulfate and the solvents were removed under reduced pressure. The residue was purified by column chromatography on silica gel (eluent MeOH-dichloromethane, gradient 0:100 to 20:80) to afford 319 (490 mg, 0.84 mmol, 84% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm: 8.42 (d, J=5.2 Hz, 1H), 7.85 (s, 1H), 7.72 (s, 1H), 7.67 (s, 1H), 7.24 (t, J=9.2 Hz, 1H), 6.98 (dd, J=13.6, 2.8 Hz, 1H), 6.72 (dd, J=9.2, 2.8 Hz, 1H), 6.62 (d, J=10.0 Hz, 1H), 6.46 (d, J=5.2 Hz, 1H), 5.05-4.95 (m, 1H), 4.23-4.07 (m, 4H), 3.91 (d, J=9.2 Hz, 1H), 3.72 (s, 3H), 1.18 (t, J=7.0 Hz, 3H), 1.11 (t, J=7.0 Hz, 3H). LRMS (M+1) 581.0 (100%).
