Procedure

To a mixture of compound 37-e (517 mg, 2.43 mmol), compound 37-j (700 mg, 2.21 mmol) in THF (5 mL) was added triethylamine (335 mg, 3.31 mmol) dropwise. The mixture was stirred overnight at room temperature. The residue obtained from removal of the solvent was purified by flash chromatography (PE:EA=1:2) to afford compound 37-k (420 mg, 38%) as a yellow solid. 1H NMR (300 MHz, CDCl3) δ 8.786 (s, 1H), 8.753-8.731 (d, J=6.6 Hz, 1H), 8.172-8.144 (d, J=8.4 Hz, 2H), 8.004-7.976 (d, J=8.4 Hz, 2H), 7.838-7.806 (m, 1H), 7.645 (s, 1H), 7.615 (s, 1H), 7.495-7.470 (s, 1H), 6.875-6.846 (d, J=8.7 Hz, 2H), 6.697-6.668 (d, J=8.7 Hz, 2H), 5.786 (s, 2H), 3.960 (s, 3H), 3.723 (s, 3H), LC-MS (ESI): 495 [M+H]+.
