To a solution of N-(phenylmethylene)alanine t-butyl ester (210 mg, 0.90 mmol), 4-(3-thienyl)phenylmethyl bromide (250 mg, 0.99 mmol), and pyridine (7 ml, 0.09 mmol) in methylene chloride (1.8 ml) are added potassium hydroxide (505 mg, 9.0 mmol) and potassium carbonate (1.24 g, 9.0 mmol). The mixture is stirred at room temperature for 2 days, then filtered and washed with methylene chloride. The filtrate and washings are concentrated in vacuo to give a crude 3-[4-(3-thienyl)phenyl]alanine as a yellow oil.
