Trimethylsilyl cyanide → (5-fluoro-8-methoxy-4H-benzo[1,3]dioxin-6-yl)-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylamino]acetonitrile

참여 물질

반응 단계

To a solution of 45 mg of Yb(OTf)3 in 3 ml of THF there were added 126 mg of 4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylamine, 153 mg of 5-fluoro-8-methoxy-4H-benzo[1,3]dioxine-6-carbaldehyde, 0.2 g of MS3A and 192 μl 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 THF. The organic layer was concentrated under reduced pressure to give (5-fluoro-8-methoxy-4H-benzo[1,3]dioxin-6-yl)-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylamino]acetonitrile (crude product).
