Procedure
By the method of Example 1, Step G, 2.10 g (0.010 mole) of 4-chloro-2,3-dihydrobenzofuran-3-on-7-yl isocyanate is reacted with 0.40 g (0.010 mole) of sodium hydride and 1.83 g (0.010 mole) of ethyl 3-amino-4,4,4-trifluorocrotonate, yielding 3-(4-chloro-2,3-dihydrobenzofuran-3-on-7-yl)-6-trifluoromethyluracil. This product is further reacted with 1.38 g (0.010 mole) of potassium carbonate and 2.80 g (0.020 mole) of methyl iodide, yielding 3-(4-chloro-2,3-dihydrobenzofuran-3-on-7-yl)-1-methyl-6-trifluoromethyluracil (Compound 30).
