Reaction Steps
1-[(4-Chlorophenyl)methyl]-5-methoxy-2-methyl-1H-indole-3-acetic acid. The procedure in Example 63, Part B, was used to react 1.35 g (5.5 mmol) of 5-methoxy-2-methyl-1H-indole-3-acetic acid ethyl ester with 240 mg (6 mmol) of 60% NaH/mineral oil and 970 mg (6 mmol) of p-chlorobenzyl chloride to give 1.4 g of 1-[(4-chlorophenyl)methyl]-2-methyl-5-methoxy-1H-indole-3-acetic acid ethyl ester that had been chromatographed on silica (20% ether/hexane→35% ether/hexane). This ester was hydrolyzed with 3 mL of 5N NaOH to give 1.23 g of crude 1-[(4-chlorophenyl)methyl]-5-methoxy-2-methyl-1H-indole-3-acetic acid.
