실험 절차

In 30 ml of formic acid, a reaction of 4.11 g of 5-bromo-2,4-diiodopyrimidine and 1.17 g of potassium thiocyanate was conducted at room temperature (20° C.) for 5 hours in a similar manner as Synthesis Example 1. Then, the reaction mixture was treated in a similar procedure as Synthesis Example 1, there was obtained a 82.4% yield of 5-bromo-2-iodo-4 thiocyanopyrimidine, m.p. 199°-202° C.
