Reaction Steps

To a solution of 4,4-dimethyl-1,4-azasilinane hydrochloride 4 (500 mg, 3.85 mmol) in EtOAc (15 mL), triethylamine (1.3 mL, 9.63 mmol) is added and stirred at 25° C. for 10 min. The reaction mixture is cooled to 0° C. and 3,4-difluoronitrobenzene (612 mg, 3.85 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 is purified by column chromatography using hexane-EtOAc mixtures and a crystalline yellow solid 9 (721 mg) is obtained in 70% yield.
