Reaction Steps

Reaction of (852) with maleimide using the procedure described in method 4a gave the adduct (CIII; Ar=2-(2-methoxyethoxy)phenyl, R10═H (853), which was used without further purification. Aromatisation of (853) with MnO2 using the procedure described in example 79 gave (854) (46%) as an orange solid, mp 157–159° C., which was used without further purification.
