Procedure

A solution of methyl (2E)-3-(5-pyrimidinyl)-2-propenoate (19.2 g, 117 mmol) and Pd/C (2 g, 1.879 mmol) in methanol (100 mL) was stirred under H2 at 50° C. overnight. The mixture was filtered through a pad of celite and concentrated to give the crude title compound as yellow oil (18 g, 55.6% yield). LCMS: rt=1.11 min, [M+H+]=167
