Procedure
2-Fluoro-6-(3-hydroxy-2-propylphenoxy)benzoic acid methyl ester (1.84 g, 4.80 mmol) was alkylated with 2-benzyloxy-1-bromo-5-ethyl-4-(3-chloro-1-propyloxy)benzene to provide crude product as an oil. Silica gel chromatography provided 2.05 g (66%) of the purified title intermediate as a colorless oil: NMR (CDCl3) 7.49 (d, J=7.1 Hz, 2H), 7.20-7.45 (m, 5H), 7.14 (t, J=8.2 Hz, 1H), 6.82 (t, J=8.5 Hz, 1H), 6.73 (d, J=8.3 Hz, 1H), 6.60 (d, J=8.4 Hz, 1H), 6.53 (s, 1H), 6.52 (d, J=8.5 Hz, 1H), 5.13 (s, 2H), 4.20 (t, J=6.0 Hz, 2H), 4.13 (t, J=6.0 Hz, 2H), 3.92 (s, 3H), 2.58 (m, 4H), 2.30 (quintet, J=6.0 Hz, 2H), 1.51 (hextet, J=7.6 Hz, 2H), 1.16 (t, J=7.9 Hz, 3H), 0.90 (t, J=7.3 Hz, 3H).
