Reaction Steps

To a mixture of 2-Amino-3-(5-chloro-benzo[b]thiophen-3-yl)-propionic acid (255.7 mg, 1.0 mmol) in methanol was added thionyl chloride (0.08 mL) at 0° C. The resulting mixture was heated at reflux for 7 h, allowed to cool to room temperature, diluted with saturated sodium bicarbonate and extracted with ethyl acetate (2×30 mL). The organic extracts were combined, washed with brine (25 mL), dried over anhydrous sodium sulfate, filtered, and concentrated to give a yellow oil (2-amino-3-(5-chloro-benzo[b]thiophen-3-yl)-propionic acid methyl ester).
