실험 절차

Bromide 3 (180 mg, 0.90 mmol) was dissolved in DMF (10 ml). Sodium azide (88 mg, 1.35 mmol) was added. The reaction mixture was then heated at 60° C. for an hour. The reaction mixture was allowed to cool and was dissolve in ethyl acetate (150 ml) and H2O (150 ml). The phases were separated and the organic phase was washed again with water (2×150 ml). The organic phase was dried over sodium sulphate, and evaporated under reduced pressure to yield 4 as an oil (134 mg, 0.83 mmol, 92%). Rf=0.70 (DCM); νmax=2094, 1694, 1607, 1207, 1167, 812, 773 cm−1; 1H NMR (300 MHz, CDCl3) δ=10.02 (s, 1H, CHO), 7.90 (d, 3J(H,H)=7.9 Hz, 2H, ArCH α to CHO), 7.48 (d, 3J(H,H)=7.9 Hz, 2H, ArCH α to CH2N3), 4.45 (s, 2H, CH2N3); 13C NMR (75 MHz, CDCl3) δ=191.6 (CHO), 142.1 (ArCCH2N3), 136.2 (ArCCHO), 130.2 (ArCH α to ArCCHO), 128.4 (ArCH α to ArCCH2N3), 54.2 (CH2N3); HRMS (ESI+): m/z calculated for C8H7N3ONa [M+Na]+: 184.0481, found 184.0497.
