Procedure

A mixture of compound 7 (3 g) and N,N-dimethyl-4-pyridinamine (1.22 g) in DCM (100 ml) was stirred till complete dissolution. 1-(3-Dimethylaminopropyl)-3-ethyl-carbodiimide hydrochloride (1.8 g) was added portionwise and the mixture was stirred at room temperature for 15 minutes. A solution of benzenemethanol (0.54 g) in DCM was added. The mixture was stirred at room temperature overnight. The solvent was evaporated. The residue was purified over silica gel on a glass filter (eluent: CH2Cl2/CH3OH 97/3 to 95/5). The pure fractions were collected and the solvent was evaporated. The residue was crystallized from ACN. The precipitate was filtered off and dried, yielding 2.06 g (62%) of phenylmethyl 6,11-dihydro-11-[1-[2-[4-(2-quinolinylmethoxy)phenyl]ethyl]-4-piperidinylidene]-5H-imidazo[2,1-b][3]benzazepine-3-carboxylate (compound 9).
