Reaction Steps

To a dry reaction vial with a screw cap was placed 2,7-dichloroquinoline-3-carboxylic acid (0.241 g, 1 mmol), sodium azide (0.078 g, 1.2 mmol) and dry DMF (3 mL) and shaken at 65-75° C. for a period of 24 h. The reaction mixture was diluted with water (100 mL), saturated with NaCl, the resulting solid was filtered and dried to give 0.100 g (41%) of the carboxytetrazole 5. TLC Rf: 0.06 (20% MeOH/EtOAc); 1H NMR (DMSO d6+CDCl3): δ 8.71 (bs, 1H), 8.60 (s, 1H), 8.30 (d, 1H, J=7.8 Hz), 7.79 (d, 1H, J=7.5 Hz); LCMS (ret. time): 21.28; MS (m/z): 249 (MH+).
