Procedure

Dissolve 2-(Carbethoxy)methylamino-4-fluorobenzonitrile (220 mg, 1 mmol) in tetrahydrofuran (3 mL) and add dropwise with stirring to a solution of potassium tert-butoxide (1 mL of a 1M solution in 1 mL tetrahydrofuran) under a nitrogen atmosphere. After 1 hour, dilute with ethyl acetate, rinse with water, dry the organic phase and concentrate in vacuo to yield the title compound (170 mg, 77%).
