Trimethylsilyl cyanide → HCID 59517170, compound

Participants

Reaction Steps

After adding 5.47 g of 4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylamine, 10.2 g of 2-fluoro-5-methoxy-3-triisopropylsilanyloxybenzaldehyde, 10 g of MS3A and 6.2 ml of trimethylsilyl cyanide to a solution of 1.94 g of Yb(OTf)3 in 100 ml of dichloromethane under a nitrogen atmosphere, the mixture was stirred for 3 days at room temperature. Ethyl acetate was added to the reaction mixture, and washing was performed with water. The organic layer was dried over anhydrous magnesium sulfate. The desiccating agent was filtered off and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate-heptane) to give the title compound (9.01 g) as a light yellow solid.
