Procedure

A 40 g quantity of tetrahydrofurfuryl alcohol and 7.2 g of sodium hydride are added to 200 ml of absolute toluene, and the mixture is stirred at 75°-80° C for 15 hours. Subsequently 14.9 g of 2-chloro-5-fluoropyrimidin-4-one is added to the reaction mixture, and the resulting mixture is heated in a sealed tube at 148° to 150° C for 5 hours for reaction. The resulting reaction mixture is treated in the same manner as in Example 6 to give 15.4 g of white crystalline 2-tetrahydrofurfuryloxy-5-fluoropyrimidin-4-one in a yield of 72.0 %, m.p. 89°-91° C.
