Participants

Reaction Steps

The ester product was obtained via a Suzuki coupling reaction using the method previously shown in Example 13, Step 6, with methyl 3-bromo-2-phenylquinoxaline-6-carboxylate (100 mg, 0.29 mmol, 1.00 equiv) and 3,4-dimethoxyphenylboronic acid (80 mg, 0.44 mmol, 1.50 equiv) as reactants. Purification by Prep-TLC (silica gel) yielded 50 mg (44%) of 3-(3,4-dimethoxyphenyl)-2-phenylquinoxaline-6-carboxylic acid as a yellow solid.
