Cyclopropanecarbonyl chloride (0.045 ml, 0.5 mmol) was added to a solution of (4-aminomethyl-3-chloro-phenyl)-(6-chloro-3-methyl-4,10-dihydro-3H-2,3,4,9-tetraaza-benzo[f]azulen-9-yl)-methanone hydrochloride from Example E106.2 (220 mg, 0.5 mmol) in dichloromethane (40 ml) and DIEA (0.30 ml, 1.7 mmol) at 0° C. The mixture was stirred for 1 h at room temperature then washed with saturated NaHCO3, brine, dried and concentrated in vacuo. The residue was purified by preparative HPLC (eluant; 0.5% 35% ammonia:9.5% methanol:90% dichloro-methane) to give a white powder identified as the title compound (135 mg, 57%).
