    摘要: A method produces a radiopharmaceutical. In the method, an H—Li exchange is made by adding an alkyllithium to an isocyanide, wherein the α-H atom of the isocyanide is replaced with an Li atom. 11CO2 is added and bonded to the α-C atom of the isocyanide. By a two-stage hydrolysis, the Li atom is replaced with an H atom and an amino group is formed from the isocyanide group, for example, by adding NH4Cl and HI. The reaction is continuously performed in particular in a microfluidic structure so that reaction times of less than 300 seconds can be achieved for the partial steps. Because the produced radiopharmaceutical has only a low half-life, the short production time has a positive effect on the yield of radioactive pharmaceutical.
