Reaction Steps

3,5-Bis-(3-formylphenyl)4-methoxymethoxybenzoic acid ethyl ester was prepared as a white solid (980 mg, 13.7%) in a similar manner to Step 1 of Example 143 from a 2:1 mixture of 3-bromo-4-methoxymethoxy-5-iodobenzoic acid ethyl ester and 3,5-dibromo-4-methoxymethoxybenzoic acid ethyl ester. There also yielded 1.6 g of a mixture of benzaldehyde and the starting halogenated compound, and 1.4 g, 20.7% of the monoarylated material as a white solid. Bis-arylated compound: 1H NMR (CDCl3) 8 1.38 (t, J=7.36 Hz, 3H); 2.59 (s, 3H); 4.33-4.42 (m, 4H); 7.62 (t, J=7.36 Hz, 2H);
