Reaction Conditions

Reaction Steps

To a solution of 25 g 2-(4-chloro-phenyl)-3-cyclopropylmethoxy-pyridine 1-oxide in 500 mL acetonitrile, 9.23 g triethylamine and 10.73 g dimethylcarbamoylchlorid were added. After 5 minutes at room temperature, 27.88 g trimethylsilylcyanid was added. The reaction mixture was stirred at 90° C. over 15 h. The reaction mixture was partitioned between water and ethyl acetate; then extracted. The organic phase was washed with brine; then dried over MgSO4 and purified by chromatography on silica gel with a gradient of heptane to heptane:ethyl acetate 2:1 to yield 15.30 g (59.26%) of the title compound as light yellow solid, MS 285.1 (M+H)+.
