Versuchsvorschrift
0.53 g of 4-(2-butynyloxy)-5,6-difluoropyrimidine and 0.39 g of 3,5-dimethylpiperidine (mixture of about cis:trans=7:3) were added to 1 ml of toluene, then the mixture was stirred at room temperature for 30 minutes. Then the reaction mixture was subjected to silica gel column chromatography to obtain 0.6 g of 4-(2-butynyloxy)-5-fluoro-6-(3,5-dimethylpiperidino)pyrimidine (referred as the present compound (4) hereinafter).
