실험 절차

For the synthesis of the title compound, 0.45 g (0.0013 mol) of 8-chloro-1-(tetrahydropyran-4-yloxy)-10,11-dihydrodibenzo[a,d]cyclohepten-5-one, 0.17 g (0.0013 mol) of 2,4-difluoroaniline, 2 spatula tips of Pd(OAc)2, 0.14 g of phosphine ligand and 0.70 g (0.0073 mol) of NaOtert-Bu in 10 ml of toluene and 2 ml of tert-BuOH are reacted by method O. Purification is carried out by column chromatography (flash; SiO2; hexane 70%/ethyl acetate 30%).
