Versuchsvorschrift

3′,4′-Methylenedioxyacetophenone (22) (150 mg, 0.914 mmol) was condensed with compound 19 (206 mg, 1.01 mmol) according to the general procedure II-A defined above. After being heated for 3 h the reaction mixture was cooled and the resulting solid filtered off and washed with cold isopropanol (3.0 mL) to afford the title compound CP30255 (250 mg, 87%) as a yellow solid, m.p. 158.7-160.5° C.
