Using a method similar to Example 710, Step 2, using 3,5-difluoro-4-hydroxy-benzaldehyde (Journal of Medicinal Chemistry (1989), 32(2), 450-5.) (2.50 g, 15.8 mmol), 6-chloronicotinonitrile (2.19 g, 15.8 mmol) and K2CO3 (3.27 g, 23.7 mmol) gives 6-(4-formyl-2,6-difluoro-phenoxy)-nicotinonitrile (2.84 g) as a white solid. 1H NMR (CDCl3): 9.95 (s, 1H), 8.39 (s, 1H), 8.02 (d, 1H), 7.58 (d, 2H), 7.25 (d, 1H).
