A method for the rapid synthesis of [ 14 C]‐phenylethanolamine (PEOH) amenable to the preparation of [ 11 C]‐PEOH was developed under anhydrous conditions. Reaction of benzaldehyde with [ 14 C]‐NaCN in the presence of crown ethers in THF yielded [ 14 C]‐cyanohydrin which was reduced to [ 14 C]‐PEOH with borane in the same solvent. The overall chemical and radiochemical yields were 33%.
