Dichloromethane → Methyl 3-(2-methoxy-5-pyridyl)propionate

Participants

Reaction Steps

A suspension of 3-(6-methoxy-pyridin-3-yl)-acrylic acid methyl ester (1.2 g, 6.21 mmol, 1 eq) and Pd/C, 10% (330 mg, 0.05 eq, 10%) was stirred in a DCM (15 ml)/absolute EtOH (15 ml) solvent mixture under hydrogen atmosphere for 1 hour at room temperature. Palladium was filtered off over a celite pad, the solvent was evaporated and obtained was 3-(6-methoxy-pyridin-3-yl)-propionic acid methyl ester (1.18 g, yield=93%, purity=95%) in form of yellowish oil.
