実験手順

2-chloropyridine-5-acetic acid (0.2 gm, 1.21 mmole), phenylboronic acid (0.16 gm, 1.3 mmole) and 50% water wet 10% Palladium carbon (0.08 gm, 0.036 mmole Pd) were added to 10 ml of 5:1 water isopropanol mixture, then Na2CO3 (0.15 gm, 1.4 mmole) dissolved in 3 ml of water was added to the above mixture, the reaction was heated at 65-70° C. overnight, the reaction was cooled to room temperature, diluted with 20 ml of 70:15:1 i-PrOH/H2O/10% NaOH, filtered, the catalyst was washed with 20 ml×3 using the above mixture, the filtrate was dried under vacuum and crude mixture was used without any purification in the next step.
