Procedure

0.5 g of 4,5,6-trifluoropyrimidine, 0.31 g of 2-butyn-1-ol and 0.62 ml of N,N-diisopropylethylamine were added to 1 ml of tetrahydrofuran, then the mixture was stirred at room temperature for 1 hour. Then the reaction mixture was subjected to silica gel column chromatography to obtain 0.52 g of 4-(2-butynyloxy)-5,6-difluoropyrimidine.
