Procedure

[6-Methoxy-2-(4-methoxyphenyl)benzo [b]thiophen-3-yl](4-hydroxyphenyl)methanone (390 mg, 1 mmol) and 2-hydroxymethyl tetrahydrofuran (153 mg, 1.50 mmol) were converted to 297 mg of the title compound by the procedure of Example 9 using 393 mg (31.5 mmol) of triphenylphosphine and 0.24 mL (1.5 mmol) of diethyl azodicarboxylate the only differences being that the chromatography eluent was 3:7 ethyl acetate:hexanes.
