Reaction Steps

To a solution of 3.5 g of Yb(OTf)3 in 250 ml of THF there were added 9.8 g of 4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylamine, 10.8 g of 8-methoxy-4H-benzo[1,3]dioxine-6-carbaldehyde, 10g of MS3A and 15 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 1000 ml of ethyl acetate. The organic layer was concentrated under reduced pressure to give the title compound (29.2 g, crude product) as a light yellow solid.
