Procedure

DIEA (0.176 ml, 1.02 mmol) and cyclopropanecarbonyl chloride (0.033 ml, 0.36 mmol) were added to a solution of (4-aminomethyl-3-methyl-phenyl)-(1-benzyl-2-methyl-4,5-dihydro-1H-1,3,6-triaza-benzo[e]azulen-6-yl)-methanone from Example E121.2 (150 mg, 0.34 mmol) in dichloro-methane (5 ml) at room temperature. The mixture was stirred for 20 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 the title compound (155 mg, 90%).
