Procedure

A mixture of 2-[3-bromophenyl]-4-[pyridin-2-yl]-1,3-oxazole (23 mg, 0.076 mmol) and zinc cyanide (112 mg, 0.96 mmol) in N,N-dimethylformamide (2 mL) was treated with Pd(PPh3)4 (74 mg, 0.064 mmol) and heated overnight at 80° C. Standard work up and chromatography afforded 6 mg (32%) of 2-[3-cyanophenyl]-4-[pyridin-2-yl]-1,3-oxazole as a white solid. 1H-NMR (CDCl3), δ (ppm): 8.61 (d, 1H), 8.45 (s, 1H), 8.38 (s, 1H), 8.36 (m, 1H),8.00 (d, 1H), 7.80 (m, 2H), 7.61 (t, 1H), 7.23 (m, 1H).
