実験手順
A mixture of 9-bromo-4,5-dihydro-6-oxa-1-thia-benzo[e]azulene-2-carboxylic acid amide (340 mg), dimethylformamide dimethyl acetal (3 ml) and toluene (2.5 mL) was heated to 100° C. for 16 hours. The solvent was then reduced in vacuo and dissolved in acetic acid (3 ml) and water (0.3 mL) and to this was added 2,4-difluorophenylhydrazine hydrochloride (265 mg). The reaction mixture was heated to 100° C. for 3 hours. The reaction mixture was then cooled, and then diluted with dichloromethane, washed with sodium carbonate solution, dried (MgSO4) and the solvent removed in vacuo. Purification using flash chromatography yielded 293. NMR: (CDCl3): 3.15 (2H, t), 4.31 (2H, t), 6.82 (1H, d), 6.86 (1H, s), 7.08-7.13 (2H, m), one proton under chloroform peak, 7.72 (1H, s), 8.10 (1H, s)
