Procedure

To a solution of intermediate 63, 3-m-tolyl-3-trifluoromethyl-3H-diazirine, (200 mg, 1 mmol) in CCl4 (4 mL) was added N-bromosuccinimide (200 mg, 1.1 mmol, re-crystallized from water), and the stirred mixture heated at 85° C. To this was added AIBN (50 mg) and the mixture heated at reflux for an additional 2.5 hrs. After cooling, the mixture was purified by column chromatography (SiO2, pentane) to provide 150 mg (Yield 54%) of the title compound as a clear oil. 1H NMR (300 MHz, CDCl3) δ ppm: 4.42 (2H, s) 7.10–7.17 (2H, m) 7.31–7.45 (2H, m).
