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

Participants

Reaction Steps

Triethylamine (0.145 ml, 1.04 mmol) and cyclopropanecarbonyl chloride (0.041 ml, 0.45 mmol) were added to a solution of (4-aminomethyl-3-methyl-phenyl)-(3,6-dimethyl-4,10-dihydro-3H-2,3,4,9-tetraaza-benzo[f]azulen-9-yl)-methanone from Example E101.2 (150 mg, 0.41 mmol) in dichloromethane (10 ml) at room temperature. The mixture was stirred for 20 h then concentrated in vacuo. The residue was purified by preparative HPLC (eluant; 0.5% 35% ammonia:9.5% methanol:90% dichloromethane) to give an off-white solid identified as the title compound (91 mg, 51%).
