Procedure

To a solution of 4-nitro-10-aza-tricyclo[6.3.1.0*2,7*]dodeca-2,4,6-triene (300 mg, 1.47 mmol) (prepared using the procedure detailed in J. Med Chem, 2005, 48, 3474-3477) in 5 ml acetone was added potassium carbonate (609 mg, 4.41 mmol) and then ethyl iodide (423 μl, 5.29 mmol). The solution was allowed to stir overnight. The reaction was evaporated under reduced pressure and partitioned between water and EtOAc. The water layer was extracted with 2×10 ml portions of EtOAc and the combined organics dried over magnesium sulfate, filtered and evaporated. The resulting brown oil was chromatographed on a 12 g Isco column using a gradient of 0-10% methanol in methylene chloride to yield 10-ethyl-4-nitro-10-aza-tricyclo[6.3.1.0*2,7*]dodeca-2,4,6-triene (280 mg, 82%) as a brown oil. 1H-NMR (CDCl3) δ 8.07 (d, J=8.1 Hz, 1H), 7.96 (s, 1H), 7.24 (d, J=8.1 Hz, 1H), 3.17 (dd, J=5.5, 4.8 Hz, 2H), 2.87 (dd, J=5.5, 4.8 Hz, 2H); 2.40-2.20 (m, 5H), 1.75 (d, J=10.6 Hz), 0.85 (d, J=10.6 Hz, 3H).
