A solution of 4-(tert-butoxycarbonylamino-methyl)-3-fluoro-benzoic acid from Example E3 (568 mg, 2.1 mmol) in dichloromethane (25 ml) at room temperature was treated with DMAP (256 mg, 2.1 mmol), DIEA (1.1 ml, 6.3 mmol) then WSCD (520 mg, 2.7 mmol). The mixture was stirred for 3 h then 6-chloro-3-methyl-3,4,9,10-tetrahydro-2,3,4,9-tetraaza-benzo[f]azulene from Example E1 (450 mg, 1.9 mmol) was added. The mixture was stirred for 4 days then washed with saturated NaHCO3 then brine, dried and concentrated in vacuo. The residue was purified by flash chromatography on silica gel (eluant; EtOAc) to yield the title compound (503 mg, 54%).
