Participants

Procedure

0.2 g of 4-(2-butynyloxy)-5,6-difluoropyrimidine and 0.09 g of pyrrolidine were added to 0.3 ml of toluene, then the mixture was stirred at room temperature for 3 hours. Then the reaction mixture was subjected to silica gel column chromatography to obtain 0.19 g of 4-(2-butynyloxy)-5-fluoro-6-pyrrolidinopyrimidine (referred as the present compound (1) hereinafter).
