Reaction Steps

To a stirred solution of 22.9 g sodium methylate in 250 ml methanol was added 37.5 g dimethyl-2-(o-methoxyphenoxy)malonate in portions within 15 min. Stirring was continued for 30 min. Then 15.8 g trifluoro-acetamidine was added followed by stirring for 20 h at room temperature. Work up was done according to the procedure described in Example 1d) to give 29.77 g 5-(o-methoxyphenoxy)-2-trifluoromethyl-pyrimidine-4,6-dione (or its tautomeric form). LC-MS: tR=3.41 min, [M+1]+=303.32.
