2-Methoxypyridne-4-boronic acid Use and Manufacturing

In a microwave vial equipped with a magnetic stir bar was added Intermediate Z (1.0 equiv), In a thick-walled reaction flask equipped with a magnetic stir bar and a Teflon screw cap was added methyl 5-chloro-1-(4-iodobenzyl)-1H-indazole-7-carboxylate (1 equiv), [l, r-bis(dicyclohexylphosphino)ferrocene]dichloropalladium(TI) (230 mg, 10 mol%) was added to a mixture of ethyl 8-bromo-7-(3-cyanophenyl)-5-(2, 4- dimethoxybenzyiammo)imidazoil, 2-c]pyrimidine-2-carboxyTate (1.7 g, 3.1 mmol), 2- methoxypyridin-4-ylboronic acid (570 mg, 3.7 mmol), and cesium carbonate (1.7 g, 5.2 mmol) in ferf-butanol (13 mL) and water (2.6 mL). The reaction mixture was purged with nitrogen, and stirred at 120 C for 3 h. The reaction mixture was then cooled to room temperature, filtered through a Celite plug with DCM and concentrated under reduced pressure. The resulting material ws purified by column chromatography eluting with 0-100% EtG Ac/hexanes to give the desired product (370 mg). LC-MS calculated for CsTLsNeOs (M-t-H)+: m/z = 565.2; found 565.4.4-((5-chloro-1-toluenesulfonyl-1H-benzo[d]imidazol-2-yl)methyl)cyclohex-1-en-1-yl trifluoromethanesulfonate20d ( 500 mg, 0.91 mmol), A solution of To a solution of tert-butyl 4-(4-((4-bromophenyl)amino)pyrimidin-2- yl)piperazine-l-carboxylate (1 equiv) and
