Reaction Steps

A mixture of thiophen-3-ylboronic acid (339 mg, 2.65 mmol), 2-oxoacetic acid hydrate (244 mg, 2.65 mmol), and 4-methoxyaniline (326 mg, 2.65 mmol) was heated under microwave irradiation at 100° C. for 1 hour. The precipitate was recovered and washed sequentially with acetonitrile, DCM and Et2O. The compound was dried under vacuum at 40° C. to obtain 2-(4-methoxyphenylamino)-2-(thiophen-3-yl)acetic acid (540 mg, 77% yield).
