Reaction Steps

A 11.7 g quantity of metal potassium is added to 200 ml of absolute toluene, and a mixture of 28 g of phenol and 100 ml of absolute toluene is further added dropwise to dissolve the potassium. Subsequently 14.9 g of 2-chloro-5-fluoropyrimidin-4-one is added to the solution, and the mixture is stirred at 100° C for 8 hours. The reaction mixture is thereafter treated in the same manner as in Example 6 to give 13.2 g of white crystalline 2-phenoxy-5-fluoropyrimidin-4-one in a yield of 64.1 %, m.p. 224°-225° C.
