9-(hetero)arylpurine derivatives has been prepared through N-arylation of 6-chloropurine with boronic acids in the presence of copper(II) acetate. Screening reaction conditions in terms of bases and solvents led to the successful coupling of a series of sterically demanding (hetero)arylboronic acids, never described so far. The coupling products were next readily converted into the target adenine derivatives. The
