5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinamine Use and Manufacturing
Under nitrogen protection, 550 mL of dioxane and 3-nitro-5-bromopyridine (20.3 g, After 0.10 mol) of pinacol borate (25.4 g, 0.10 mol) and potassium acetate (14.7 g, 0.15 mol), after stirring uniformly, the catalyst PdCl2dppf (0.74 g, 0.001 mol) was finally added, and the temperature was slowly raised to 80- 90 ° C, Stir the reaction for 2-3 h. After the completion of the GC reaction, the reaction was stopped by cooling, and the reaction solution was filtered through celite to obtain a dark-black reaction solution. After charging at 1 atm of hydrogen, the mixture was reacted at room temperature overnight. After the reaction was completed, the activated carbon was decolorized, and the filtrate was distilled under reduced pressure until no liquid was poured. /Heptane mixed solvent is cooled and beaten for half an hour, filtered to obtain a light gray crude product, heated again with ethanol, and then cooled down, and the filter cake is rinsed with -20 ° C anhydrous ethanol, and dried to obtain a pale yellow solid 15.6 g, yield 71percent, HPLC purity 97.9percent
