Reaction Steps

A mixture of 3-(2-pyridyl)-5-(3-cyano-5-hydroxyphenyl)-1,2,4-oxadiazole (30 mg, 0.12 mmol), potassium carbonate (32 mg, 0.23 mmol) and 2-iodopropane (17 μL, 0.17 mmol) in N,N-dimethylformamide (1 mL) was heated in a sealed vial at 90° C. for 2 hours. The reaction was cooled, diluted with dichloromethane, washed with water (3×) and saturated brine, filtered and concentrated. Silica gel chromatography using a hexanes/ethyl acetate/dichloromethane (3.5:0.5:4) afforded 24 mg (68%) of 3-(2-pyridyl)-5-(3-cyano-5-isopropoxyphenyl)-1,2,4-oxadiazole: 1H NMR (CDCl3), δ (ppm): 8.86 (d, 1H), 8.23 (d, 1H), 8.12 (s, 1H), 7.98 (s, 1H), 7.91 (m, 1H), 7.49 (m, 1H), 7.36 (s, 1H), 4.71 (m, 1H), 1.41 (m, 6H).
