実験手順

A mixture of 4-(tert-butoxycarbonylamino-methyl)-3-fluoro-benzoic acid from Example E3 (1.38 g, 5.1 mmol) and 3,6-dimethyl-3,4,9,10-tetrahydro-2,3,4,9-tetraaza-benzo[f]azulene from Example E2 (11.0 g, 4.7 mmol) in di-chloromethane (20 ml) at room temperature was treated with DIEA (2.44 ml, 14.0 mmol), DMAP (627 mg, 5.1 mmol) and WSCD (1.16 g, 6.1 mmol). The solution was heated at re-flux for 2 days then washed with saturated NaHCO3 then brine, dried and concentrated in vacuo. The residue was purified by flash chromatography on silica gel through an isolute (eluant; EtOAc) to yield the title compound (1.29 g, 59%).
