실험 절차

A mixture of compound 4 (8.32 g) and methyl methylthiomethyl sulfoxide (MMTS) (4.5 g) in THF (100 ml) and benzyltrimethyl ammonium hydroxide (40% in methanol; 20 ml) was stirred and refluxed overnight. The solvent was evaporated. The residue was taken up in water and extracted with DCM. The organic layer was separated, dried (MgSO4), filtered and the solvent was evaporated. Toluene was added twice and evaporated again. The residue was taken up in methanol (50 ml). HCl gas was bubbled through the mixture, cooled on an ice bath, for 30 minutes. The mixture was stirred overnight. The solvent was evaporated. The residue was taken up in water, alkalized with K2CO3 and extracted with DCM. The organic layer was separated, dried, filtered and the solvent was evaporated. The residue was purified over silica gel on a glass filter (eluent: CH2Cl2/CH3OH95/5). The pure fractions were collected and the solvent was evaporated. The residue was crystallized from ACN. The precipitate was filtered off and dried, yielding 2.7 g (30%) of methyl 6,11-dihydro-11-[1-[2-[4-(2-quinolinylmethoxy)phenyl]ethyl]-4-piperidinylidene]-5H-imidazo[2,1-b][3]benzazepine-3-acetate (compound 5).
