Participants

Reaction Steps

To a solution of 4-[4-(1-methylpiperidin-4-yloxy)-9,10-dihydro-4H-3,10a-diaza-benzo[f]azulen-2-yl]-phenylamine (example 16) (100 mg, 0.258 mmole) in CH2Cl2 (2 mL) is added NEt3 (72 μL, 0.515 mmole) and propylisocyanate (36 μL, 0.387 mmole). The reaction mixture is stirred at room temperature for 24 hours. Solvent is removed under reduced pressure. AcOEt is added to the residue and the organic phase is washed with water and dried over magnesium sulphate, filtered and the solvent is removed under reduced pressure. The residue is purified by silica gel chromatography using (CH2Cl2:MeOH) as eluent with a gradient from (100:0) to (90:10) to afford 1-{4-[4-(1-methylpiperidin-4-yloxy)-9,10-dihydro-4H-3,10a-diaza-benzo[f]azulen-2-yl]-phenyl}-3-propyl-urea melting at 130° C.
