Reaction Steps
A mixture of 3-(2-pyridyl)-5-(3-cyano-5-hydroxyphenyl)-1,2,4-oxadiazole (31 mg, 0.12 mmol), potassium carbonate (32 mg, 0.24 mmol) and hexyl bromide (25 μL, 0.18 mmol) in N,N-dimethylformamide (1 mL) was heated in a sealed vial at 90° C. for 35 minutes. The reaction was cooled, diluted with dichloromethane, washed with water (3×) and saturated brine, filtered and concentrated. Silica gel chromatography using 2% methanol in dichloromethane afforded 18 mg (39%) of 3-(2-pyridyl)-5-(3-cyano-5-(2-hydroxyethoxy)phenyl)-1,2,4-oxadiazole: 1H NMR (CDCl3), δ (ppm): 8.86 (d, 1H), 8.23 (d, 1H), 8.13 (s, 1H), 8.00 (s, 1H), 7.91 (dd, 1H), 7.49 (dd, 1H), 7.38 (s, 1H), 4.09 (t, 2H), 1.84 (m, 2H), 1.49 (m, 2H), 1.37 (m, 4H), 0.93 (t, 3H).
