Methyl 2-(3-phenoxyphenoxy)phenylacetate was prepared from 3-phenoxyphenol and 2-bromobenzaldehyde by the steps described in Example 1 for the preparation of methyl 2-(3-methoxyphenoxy)phenylacetate. This was the converted into (E)-methyl 3-methoxy-2-[2-(3-phenoxyphenoxy) phenyl]propenoate [1H n.m.r (250 MHz) 3.61 (3H, s), 3.78 (3H, s), 6.68-7.35 (13H, m), 7.48 (1H, s) ppm] using sodium hydride and methyl formate, and then potassium carbonate and dimethyl sulphate, using the procedure described in Example 1 for the preparation of (E)-methyl 2-[2-(3-hydroxyphenoxy)phenyl]-3-methoxypropenoate, except that just 2 equivalents of sodium hydride were used in this case.
