Dichloromethane → 3-(2-Methyl-pyrimidin-5-yl)-propionic acid methyl ester

Participants

Reaction Steps

3-(2-Methyl-pyrimidin-5-yl)-acrylic acid methyl ester (450 mg, 2.53 mmol, 1 eq) and Pd/C, 10% (0.05 eq, 135 mg) were stirred in a DCM (4 ml)/ethanol (4 ml) mixture under hydrogen atmosphere at room temperature for 20 minutes. Pd/C was filtered off over a celite pad, the solvent was evaporated and obtained was 3-(2-methyl-pyrimidin-5-yl)-propionic acid methyl ester (450 mg, yield=90%, purity=88%).
