실험 절차

To a solution of 9-cyano-4,5-dihydro-6-oxa-1-thia-benzo[e]azulene-2-carboxylic acid (300 mg) in dichloromethane (10 mL) was added DMF (1 drop) and oxalyl chloride (0.165 mL) and the reaction stirred at room temperature for 30 min. The solvent was then reduced in vacuo and the residue redissolved in acetonitrile (10 mL). To this solution was added 2-chloro-N-methylaniline (0.165 mL) and potassium carbonate (308 mg) and the reaction stirred at room temperature for 16 h. The mixture was partitioned between water (40 mL) and ethyl acetate (30 mL). The organic layer was dried (Na2SO4), reduced in vacuo and purified on silica to give 120. NMR: (CDCl3): 3.08 (t, 2H, CH2, J=5.00 Hz), 3.41 (s, 3H, CH3), 4.29 (t, 2H, CH2, J=5.02 Hz), 6.92 (s, H, ArH), 7.03 (d, H, ArH, J=8.43 Hz), 7.38-7.47 (m, 4H, 4×ArH), 7.57 (m, H, ArH), 7.72 (d, H, ArH, J=1.65 Hz). MS: (ESI+) MH+ 395
