実験手順

A solution of 4-(tert-butoxycarbonylamino-methyl)-3-chloro-benzoic acid from Example E2b (568 mg, 2.0 mmol) in dichloromethane (25 ml) at room temperature was treated with DMAP (244 mg, 2.0 mmol), DIEA (11.0 ml, 6.0 mmol) then WSCD (500 mg, 2.6 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 (430 mg, 1.8 mmol) was added. The mixture was stirred for 4 days then washed with saturated NaHCO3, brine, dried and concentrated in vacuo. The residue was purified by flash chromatography on silica gel (eluant; EtOAc) to yield the title compound (570 mg, 63%).
