Reaction Conditions

Reaction Steps

To a solution of 5-(4-cyclohexyl-phenoxymethyl)-4,5-dihydro-oxazol-2-ylamine (350 mg, 1.28 mmol) in ethanol (6 mL) was added ethyl acrylate (255.8 mg, 2.56 mmol). The reaction mixture was heated in a microwave oven at 150° C. for 40 min. The solvent was removed under vacuum, and the residue purified via flash column chromatography (silica gel, 0.5-12% EtOH/CH2Cl2) to afford an oil, which was dissolved in a small amount of methylene chloride and to which was then added heptane. A white solid precipitated to afford 110 mg of 2-(4-cyclohexyl-phenoxymethyl)-2,3,5,6-tetrahydro-oxazolo[3,2-a]pyrimidin-7-one.
