Reaction Steps

To a solution of 1-(5-bromopyridin-2-yl)propan-1-ol (0.3 g, 1.38 mmol) in toluene (8 mL) and ethanol (4 mL) was added 4-cyano phenyl boronic acid (0.244 g, 1.6 mmol) and a 2 M solution of aq. Na2CO3. The reaction mixture degassed with argon, Pd(PPh3)4 (0.08 g, 0.069 mmol) was added, the reaction mixture was again degassed with argon for 10 min, and heated to 80° C. for 4 h. The reaction mixture was evaporated under vacuum to remove ethanol, the reaction mixture was diluted with water (10 mL), extracted with ethyl acetate (100 mL), dried over sodium sulphate, filtered and evaporated under reduced pressure to obtain crude product. The crude product was purified by a Biotage Isolera® One column (using 15% ethyl acetate and hexane) to give 4-(6-(1-hydroxypropyl)pyridin-3-yl)benzonitrile (0.15 g, 45.45% yield). 1H NMR (400 MHz DMSO-d6): δ 8.78 (s, 1H), 7.89 (dd, 1H), 7.78 (d, 2H); 7.69 (d, 2H), 7.39 (d, 1H), 4.77 (t, 1H), 3.90 (s, 1H), 1.91-1.81 (m, 2H), 0.99 (t, 3H).
