Versuchsvorschrift

A mixture of methyl (2E)-3-[2-(methyloxy)-5-pyrimidinyl]-2-propenoate (24.0 g, 124 mmol) and Pd/C (300 mg) in methanol (250 mL) was stirred at 50° C. under H2 for two days, filtered through a pad of Celite and concentrated to give the title compound as a yellow oil (20 g, 68%), which was used without further purification. LCMS: rt=1.17 min, [M+H+]=196
