Reaction Conditions

Temperature60 °C

Reaction Steps

1-(5-fluoropyridin-2-yl)cyclopropanecarbonitrile (880 mg) was dissolved in ethanol (10 ml) before slow, dropwise addition of 96% sulfuric acid (10 ml). The reaction mixture was allowed to stir at 60° C. for 24 hr. Upon cooling, NaHCO3 was added until pH 8 and then the solution extracted three times with ethyl acetate, the organics were washed with brine and dried over Na2SO4 before concentration in vacuo.
