Procedure

A mixture of compound 6-E (0.300 g, 0.75 mmol) and K2CO3 (0.218 g, 1.58 mmol) in DMF (5 mL) was cooled in an ice bath and treated with a solution of 4-trifluoromethoxybenzyl bromide (0.132 mL, 0.83 mmol) in DMF (1 mL) and stirred at ambient temperature for 18 hours. The solution was partitioned between EtOAc and water, and the organic phase was separated, washed with water (3×) then brine and dried over sodium sulfate. The solvent was evaporated in vacuo, and the residue was pre-absorbed on silica gel and purified by flash chromatography, using a gradient of EtOAc (10-50%) in heptanes as the eluant, to give the Compound 118, as a colorless solid (0.330 g, 82%). 1H-NMR (CDCl3): δ 8.17 (d, J=8.6 Hz, 2H), 7.85 (d, J=8.6 Hz, 8H), 7.69-7.74 (m, 1H), 7.41 (dd, J=9.9, 5.0 Hz, 1H), 7.29 (d, J=8.6 Hz, 2H), 7.03-7.14 (m, 3H), 4.74 (s, 2H), 3.97 (s, 3H), 2.26 (s, 3H); MS: m/z 538.0 (MH+).
