実験手順

To a solution of 230 mg of Yb(OTf)3 in 20 ml of dichloromethane there were added 650 mg of 4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylamine, 773 mg of 8-ethyl-4H-benzo[1,3]dioxine-6-carbaldehyde, 1g of MS3A and 0.8 ml of trimethylsilyl cyanide under a nitrogen atmosphere, and the mixture was stirred overnight at room temperature. The reaction mixture was filtered through celite, and the celite was washed with 100 ml of ethyl acetate. The organic layer was concentrated under reduced pressure to give (8-ethoxy-4H-benzo[1,3]dioxin-6-yl)-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylamino]acetonitrile (crude product).
