Participants

Reaction Steps

Isobutyryl chloride (0.07 ml, 0.07 mmol) was added to a solution of (4-aminomethyl-3-methyl-phenyl)-(9-chloro-2-methyl-4,5-dihydro-1H-1,3,6-triaza-benzo[e]azulen-6-yl)-methanone from Example E125.3 (24 mg, 0.07 mmol) in dichloromethane (3 ml) and DIEA (0.10 ml, 0.57 mmol) at 0° C. The mixture was stirred for 20 h at room temperature then solvents were removed in vacuo. The residue was purified by flash chromatography on silica gel (eluant; 5% methanol:95% dichloromethane to 10% methanol:90% di-chloromethane) to give a colourless oil identified as the title compound 24 mg, 85%).
