Versuchsvorschrift

To a solution of benzylic alcohol 18 (300 mg, 1.13 mmol), triphenylphosphine (357 mg, 1.36 mmol) and phthalimide (200 mg, 1.36 mmol) in dry THF (10 mL) was added DIAD (0.26 mL, 1.36 mmol) under an N2 atmosphere. The resulting mixture was stirred at 25° C. for 24 hours after which solvents were evaporated under reduced pressure. The crude product mixture was purified by chromatography on silica gel to give the title compound 19 as a white (300 mg, 0.762 mmol, 67%). 1H NMR (400 MHz, CDCl3) δ 8.68 (bs, 2H), 7.88-7.83 (m, 2H), 7.78-7.75 (m, 2H), 5.13 (s, 2H); 13C NMR (75 MHz, CDCl3) δ 168.1, 151.8, 142.7, 135.1, 132.4, 124.4, 43.3; MS (ESI) Calculated for C14H9N2O2Br2[M+H]+: 397.04. Found: 396.90.
