extraction d'or facile

a facile method was developed to purify 218 ffluoroethyl azide (18 ffea) using a c18 cartridge and an oasis hlb cartridge in series, in which 18 ffea was exclusively trapped on the hlb cartridge.18 ffea can be eluted for reactions in solution; alternatively click labeling can be carried out on the hlb cartridge itself by loading an alkyne substrate and copper (i) catalyst dissolved
