実験手順

A mixture of 4-(tert-butoxycarbonylamino-methyl)-2-fluoro-benzoic acid from Example E2 (1.35 g, 5.0 mmol), 3-methyl-3,4,9,10-tetrahydro-2,3,4,9-tetraaza-benzo[f]azulene from Example E11 (11.0 g, 5.0 mmol) and PyBroP (3.03 g, 6.5 mmol) in dichloromethane (25 ml) and DIEA (1.31 ml, 7.5 mmol) was heated at reflux for 18 h. After cooling to room temperature, the mixture was washed with 5% KHCO3, 1M HCl then brine, dried and concentrated in vacuo. The residue was purified by flash chromatography on silica gel (eluant; EtOAc) to yield the title compound (1.25 g, 56%).
