Reaction Steps

To a solution of 4,4-dimethyl-1,4-azasilinane hydrochloride 4 (950 mg, 7.35 mmol) in EtOAc (15 mL), triethylamine (2.5 mL, 18.37 mmol) is added and stirred at 25° C. for 10 min. The reaction mixture is cooled to 0° C. and 1,2,3-trifluoro-5-nitrobenzene (1.29 g, 7.35 mmol) is added drop wise and allowed to stir at 25° C. for 6 h. Water is then added and the organic layer is separated. The aqueous layer is extracted with EtOAc (2×10 mL) and the solvent is removed under reduced pressure. The product obtained is purified by column chromatography using hexane-EtOAc mixtures to give the product as a crystalline yellow solid 9a (1.32 g) in 63% yield.
