Reaction Steps

A mixture of 4-fluorophenylacetic acid (9 g, 58.4 mmol), 4-pyridinecarboxaldehyde (5.6 ml, 58.6 mmol), pyridine (6 ml) and acetic anhydride (6 ml) was heated at 150° C. for 1 h followed by evaporation and co-distillation with water. The resulting material crystallized on addition of ethanol. The solids were filtered and washed with ethanol and ethyl acetate to provide the title compound.
