実験手順
8-Iodo-3-phenylsulfonyl-quinoline (D6) (190 mg, 0.48 mmol), N-methyl-piperazine (48 mg, 0.48 mmol), sodium tertbutoxide (65 mg, 0.68 mmol), di-palladium tetrakis-(dibenzylidine acetone) [Pd2(dba)3] (88 mg, 0.1 mmol) and 1,1′-diphenylphosphino ferrocene (161 mg, 0.3 mmol) were suspended in degassed dry dioxan (2 ml). The mixture was stirred under argon at 40° C. for 16 hours. The solvent was removed and the residue subjected to flash chromatography on silica gel (eluting with dichloromethane-methanol aq. ammonia) to give the title compound (E1), identical spectroscopically to that prepared by the earlier methods.
