실험 절차

NaH (60%, 144 mg, 1.317 mmoL) was added into 8-(tert-butyl-dimethyl-silanyloxy)-6,11-dihydro-5-thia-11-aza-benzo[a]fluorene (440 mg, 1.197 mmoL) in DMF (5 mL) at 0° C. After 10 minutes, 1-[2-(4-chloromethyl-phenoxy)-ethyl]-piperidine (382 mg, 1.317 mmoL) was added dropwise into the reaction at 0° C. The reaction mixture was slowly warmed to room temperature over 2 hours. The reaction mixture was then partitioned between EtOAc and saturated NH4Cl. The aqueous phase was extracted two times with EtOAc. The organic layers from the two extractions were combined, washed with water, brine, dried over anhydrous Na2SO4, filtered and concentrated to yield a brown oil. The crude material (the oil) was then purified by column chromatography (silica gel, first EtOAc then CH2Cl2:MeOH 4:1 as eluent) to yield 8-(tert-butyl-dimethyl-silanyloxy)-11-[4-(2-piperidin-1-yl-ethoxy)-benzyl]-6,11-dihydro-5-thia-11-aza-benzo[a]fluorine as a pale foam and 11-[4-(2-piperidin-1-yl-ethoxy)-benzyl]-6,11dihydro-5-thia-11-aza-benzo[a]fluoren-8-ol as a yellow solid.
