Procedure

A mixture of 2-[2-(4-fluorophenyl)ethyl]benzonitrile (8.03 g, 35.6 mmol, 1 equiv) and aq. NaOH (10N; 16 mL, 160 mmol, 4.5 equiv) in ethylene glycol (100 mL) was heated to 190° C. for 69 h. After allowing the reaction mixture to cool, H2O (300 mL) was added, followed by 12N HCl (16 mL) This mixture was extracted with CHCl3 (1×100 mL) and the organic layer was then washed with H2O (2×50 mL). The organic layer was dried (anh. Na2SO4) and rotary evaporated (90° C.). This provided 7.44 g (85.4%) of a light-yellow solid.
