Participants

Reaction Steps

By the method of Example 1, Step H, 8.95 grams (0.024 mole) of 3-(2,5-dichloro-3-methoxyphenylmethyl)-6-trifluoromethyluracil, 5.03 grams (0.036 mole) of dimethyl sulfate, and 8.99 grams (0.048 mole) of potassium carbonate were reacted in 800 mL of acetone, yielding 6.0 grams of 3-(2,5-dichloro-3-methoxyphenylmethyl)-1-methyl-6-trifluoromethyluracil as a viscous, yellow oil, which became a glass upon cooling. This glass crystallized after standing for a period of time, m.p. 117°-123° C. The NMR spectrum was consistent with the proposed structure.
