Procedure

A 300 ml quantity of absolute sec-butanol, 5.8 g of metal sodium and 14.9 g of 2-chloro-5-fluoropyrimidin-4-one are treated in the same manner as in Example 6 to obtain crystals, which are then recrystallized from a water-ethanol mixture to give 17.0 g of white crystalline 2-sec-butoxy-5-fluoropyrimidin-4-one in a yield of 91.4%, m.p. 104°-105° C.
