2-%28Dimethylamino%29pyridine-5-boronic+acid+pinacol+ester that is, 2 - (dimethylamino) pyridine - 5 - boronic acid pinacol ester, the synthesis method is as follows:
First, 2 - chloro - 5 - bromopyridine is used as the starting material. In a suitable reaction vessel, the corresponding solution of dimethylamine is added.
