실험 절차

3′,4′-Dimethoxyacetophenone (23) (150 g, 0.832 mmol) was condensed with compound 19 (187 mg, 0.914 mmol) according to the general procedure II-A defined above. After being heated for 3 h the mixture was cooled and the resulting solid filtered off and washed with cold isopropanol (3.0 mL) to afford the title compound CP30257 (222 mg, 81%) as a white solid, m.p. 118.4-121.0° C.
