Ethanol → 3-(4-Ethylamino-2-phenylamino-pyrimidin-5-yl)propionic acid ethyl ester

Participants

Reaction Steps

A mixture of ethyl 3-(4-ethylamino-2-phenylamino-pyrimidin-5-yl)acrylate (152 mg, 0.48 mmol) and 5% palladium on carbon in a solvent mixture of ethanol and tetrahydrofuran was hydrogenated under pressure. The catalyst was filtered off and the filtrate concentrated. The residue was purified by flash chromatography eluting with 2:1 ethyl acetate:hexane to give 72 mg (47%) of 3-(4-ethylamino-2-phenylamino-pyrimidin-5-yl)propionic acid ethyl ester, mp 106-107° C.
