To a solution of 4-{1-ethyl-1-[4-(3-hydroxy-3-methylbutyl)-3-methyl-phenyl]propyl}-2-methylphenol (0.14 g, 0.40 mmol) in anhyd DMF (2 mL) was added CsF (67 mg, 0.44 mmol), Cs2CO3 (26 mg, 80 □ mol) and (S)-glycidol (29 μL, 0.44 mmol). The reaction mixture was heated at 80° C. for 4 h. After cooling, the mixture was diluted with DCM (40 mL), washed with H2O (2×40 mL), 1 N HCl (20 mL) and brine, then dried (Na2SO4) and concentrated under reduced pressure. The crude material was chromatographed (silica, EtOAc/DCM, 0:100 to 75:25) to provide the title compound (80 mg, 47%) as a white powdered solid: 1H-NMR (CD2Cl2) δ 7.01 (1H, d, J=8.1), 6.96 (1H, dd, J=2.3, 8.3), 6.88-6.94 (3H, m), 6.73 (1H, d, J=8.3), 3.97-4.11 (3H, m), 3.77-3.84 (1H, m), 3.69-3.76 (1H, m), 2.62 (2H, m), 2.53 (1H, d, J=5.1), 2.24 (3H, s), 2.16 (3H, s), 2.05 (4H, q, J=7.3), 1.99 (1H, t, J=6.1), 1.67 (2H, m), 1.27 (6H, s), 0.58 (6H, t, J=7.3); 13C-NMR (CD2Cl2) δ 155.0, 147.2, 142.0, 138.4, 135.7, 131.2, 130.4, 128.5, 126.9, 126.3, 126.2, 110.9, 71.4, 71.3, 70.1, 64.6, 49.3, 45.2, 29.8, 29.6, 28.3, 20.0, 17.0, 8.9.
