Reaction Steps

To a solution of 1-(5-bromopyridin-2-yl)propan-1-ol (0.7 g, 3.2 mmol) in toluene (15 mL) and ethanol (8 mL) was added 2-cyano phenyl boronic acid (0.57 g, 3.8 mmol) and a 2M solution of aq. Na2CO3. The reaction mixture was degassed with argon, Pd(PPh3)4 (0.187 g, 0.162 mmol) was added, the reaction mixture was again degassed with argon for 10 min, and the reaction heated to 100° C. for 3 h. The reaction mixture was evaporated under vacuum to remove ethanol, diluted with water (40 mL), extracted with ethyl acetate (200 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 20% ethyl acetate and hexane) to give 2-(6-(1-hydroxypropyl)pyridin-3-yl)benzonitrile. (0.150 g, 19.4% yield). 1H NMR (400 MHz DMSO-d6): δ 8.67 (s, 1H), 8.02-7.97 (m, 2H), 7.82 (t, 1H), 7.69 (d, 1H), 7.63-7.60 (m, 2H), 1.83-1.68 (m, 2H), 0.89 (t, 3H): LC-MS m/z calcd for [M+H]+ 239.11. found 239.0.
