Versuchsvorschrift
A mixture of ethyl 2-pyrimidinyloxyacetate (GB2373186, step i ex 368) (4.4 g, 24.15 mmol) and hydrazine hydrate (5 mL, 160 mmol) in isopropanol (30 mL) was heated under reflux for 1 hour. The mixture was then cooled and concentrated under reduced pressure and the residue was purified by column chromatography on silica gel using dichloromethane:methanol:0.88 ammonia (100:0:0 to 100:10:1) to provide the title compound, 600 mg.
