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-chloro-2-phenylquinoxaline-6-carboxylate (100 mg, 0.34 mmol, 1.00 equiv) and 4-ethoxyphenylboronic acid (61 mg, 0.37 mmol, 1.10 equiv) As reactants. Purification via silica gel column (ethyl acetate/petroleum ether (1:5)) yielded 55 mg (43%) of methyl 3-(4-ethoxyphenyl)-2-phenylquinoxaline-6-carboxylate as a yellow powder.
