Versuchsvorschrift
A mixture of α-heptafluoropropylacrylic acid (240 mg; 1.0 mmole), urea (64 mg; 1.1 mmoles) and acetic anhydride (0.6 ml) was heated at 100° C. with stirring for 40 minutes. Then, ethanol (3 ml) was added to the reaction mixture to give 180 mg (yield: 64%) of 5-heptafluoropropyldihydrouracil as colorless crystals. m.p.: 223°-224 (decomp.).
