Reaction Steps
After adding 3.12 g of 4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylamine, 3.3 g of MS3A, 1.11 g of Yb(OTf)3 and 4.75 ml of trimethylsilyl cyanide to a solution of 5.0 g of 4-t-butyldimethylsilanyloxy-3-methoxybenzaldehyde [CAS No. 69404-94-0] in 98 ml of dichloromethane under a nitrogen atmosphere, the mixture was stirred at room temperature for 23 hours. Next, 500 ml of ethyl acetate was added to the reaction mixture, the reaction mixture was filtered through celite, and the celite was washed with ethyl acetate. The organic layers were combined and washed with water and saturated brine, and then dried over anhydrous sodium sulfate. The desiccating agent was filtered off, and the filtrate was concentrated under reduced pressure to give the title compound (8.45 g) as a crude product.
