Versuchsvorschrift

Sodium methoxide (725 mg, 13.42 mmol) was added to a solution of 2-Chloro pyridine-5-carbonitrile (1.8 g, 13.04 mmol) in MeOH:dioxane (40 ml, 1:1) at 0° C., then stirred for 30 minutes at 0° C., and 1 hour at room temperature. The reaction was diluted with EtOAc (200 ml) and H2O (100 ml), organic layer separated, dried over Na2SO4, filtered and solvent evaporated to yield title compound 1BX as a white solid (2.6 g, 100%) MS (MH 171)
