Procedure

Cyclopropanecarbonyl chloride (26 mg, 0.25 mmol) was added to a solution of (4-aminomethyl-3-methyl-phenyl)-(2-methyl-4,5-dihydro-1-oxa-3,6-diaza-benzo[e]azulen-6-yl)-methanone hydrochloride from Example E119.2 (85 mg, 0.22 mmol) in dichloromethane (5 ml) and triethylamine (to pH9) at room temperature. The mixture was stirred for 1 h then purified by flash chromatography on silica gel (eluant; 10% methanol:90% dichloromethane) to give a white solid identified as the title compound (62 mg, 67%).
