Procedure

A solution of AlCl3 (203 mg, 1.52 mmol) in anhydrous anisole (750 μl) was added to 38 (191 mg, 0.31 mmol) in anhydrous anisole (750 μl) and the resulting solution was stirred at room temperature for 18 hours. The reaction was diluted with MeOH (750 μl) and the solvent was concentrated. The residue was purified via column chromatography (SiO2, 1:1 EtOAc:Hexanes) to give 39 as a light yellow amorphous solid (126 mg, 77%): 1H NMR (CDCl3, 500 MHz) δ 7.56 (m, 1H), 7.50 (d, J=8.7 Hz, 1H), 7.47 (dd, J=8.6, 2.3 Hz, 1H), 7.36 (d, J=2.0 Hz, 1H), 7.29 (d, J=2.2 Hz, 1H), 7.25 (m, 2H), 7.12-7.06 (m, 3H), 7.00 (dd, J=8.7, 2.1 Hz, 1H), 6.80 (m, 2H), 6.77 (m, 1H), 6.73 (d, J=8.7 Hz, 1H), 6.59-6.55 (m, 2H), 5.43 (s, 1H), 5.15 (s, 2H), 3.77 (s, 3H), 3.71 (s, 3H), 3.62 (s, 3H); 13C NMR (CDCl3, 125 MHz) δ 170.2, 159.3, 159.0, 157.6, 154.2, 139.7, 139.0, 133.1, 132.4, 130.5, 130.1, 130.1 (2C), 130.0, 129.5, 128.9, 128.9, 128.0, 127.5, 127.3, 125.9, 122.1, 118.7, 114.7, 114.0 (2C), 113.2, 110.4, 109.5, 55.7, 55.4, 55.3, 54.0; IR (film) νmax 3236, 2934, 2835, 1599, 1508, 1456, 1437, 1394, 1248, 1177, 1036 cm−1; HRMS (ESI+) m/z: [M+H]+ calcd for C33H29NO5, 520.2124; found, 520.2120.
