Cyclopropanecarbonyl chloride → Cyclopropanecarboxylic Acid 4-(3,6-dimethyl-4,10-dihydro-3H-2,3,4,9-tetraaza-benzo[f]azulene-9-carbonyl)-2-fluoro-benzylamide

Participants

Reaction Steps

DIEA (0.08 ml, 0.46 mmol) and cyclopropanecarbonyl chloride (0.013 ml, 0.14 mmol) were added to a solution of (4-aminomethyl-3-fluoro-phenyl)-(3,6-dimethyl-4,10-dihydro-3H-2,3,4,9-tetraaza-benzo[f]azulen-9-yl)-methanone hydrochloride from Example E98.2 (57 mg, 0.14 mmol) in dichloromethane (10 ml) at 0° C. The mixture was stirred for 90 min at room temperature then diluted with dichloromethane, 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 solid identified as the title compound (33 mg, 54%).
