Versuchsvorschrift

A solution of compound 86b (350 mg, 1 eq.) and compound 46b (480 mg, 6 eq.) in N-methylpyrrolidone (5 mL) was heated at 200° C. for 30 min. After the reaction mixture was cooled to room temperature, water was added. The mixture was extracted with EtOAc, dried over Na2SO4, filtered, and concentrated under reduced pressure. The crude material was purified by chromatography on silica gel (EtOAc/DCM). Recrystallisation in diethylether gave compound 88b as a white solid in 49% yield.
