Hydrochloric Acid → 2,3a,10-trimethyl-6-phenyl-2,3,3a,4-tetrahydro-1H-indolo[3,2,1-ij][1,6]naphthyridine

참여 물질

반응 단계

A solution of p-tolylhydrazine.HCl (13 mg, 0.084 mmol) and 1,3-dimethyl-3-(3-oxo-3-phenyl-propyl)-piperidin-4-one (22 mg, 0.084 mmol) in ethanolic-HCl (5 mL) was stirred at 84° C. for 12 h. The reaction mixture was concentrated under reduced pressure and the residue was basified with saturated aqueous NaHCO3 solution. The product was extracted with EtOAc (3×15 mL), organic layer dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by reverse phase HPLC to obtain 2,3a,10-trimethyl-6-phenyl-2,3,3a,4-tetrahydro-1H-indolo[3,2,1-ij][1,6]naphthyridine.
