실험 절차

To a mixture obtained by adding 110.0 g of 4,6-difluoropyrimidine, 132.3 g of potassium carbonate and 19.2 g of triethylamine to 220.0 g of toluene, 69.8 g of 2-butyn-1-ol is added dropwise at 25 to 30° C. over one hour, followed by stirring at 30° C. Then, 220.0 g of water is added dropwise into the reaction mixture, followed by stirring. Then, 152.4 g of 3-trifluoromethylpyrrolidine is added dropwise and, after the mixture is stirred at 30° C., the reaction mixture is allowed to stand. After separating into the organic layer and the aqueous layer, the aqueous layer is removed and the organic layer is washed once with 220.0 g of 5% hydrochloric acid and then washed once with 220.0 g of water. The organic layer is concentrated to obtain 4-(2-butynyloxy)-6-(3-trifluoromethylpiperidino)pyrimidine (hereinafter referred to as the present compound (2)).
