DIEA (0.135 ml, 0.78 mmol) and isobutyryl chloride (0.029 ml, 0.27 mmol) were added to a solution of (4-aminomethyl-3-fluoro-phenyl)-(6-chloro-3-methyl-4,10-dihydro-3H-2,3,4,9-tetraaza-benzo[f]azulen-9-yl)-methanone hydrochloride from Example E102.2 (110 mg, 0.26 mmol) in dichloromethane (3 ml) at room temperature. The mixture was stirred for 1 h, washed with saturated NaHCO3 then brine, dried and concentrated in vacuo. The residue was purified by preparative HPLC (eluant; 0.5% 35% ammonia:9.5% methanol:90% dichloromethane) to give a white powder identified as the title compound (85 mg, 71%).
