BORONIC ACID, [3-(1-NAPHTHALENYL)PHENYL]- Use and Manufacturing

1, 3PhenylDiboronAcid 1.99g (12mmol), 1- bromo-naphthalene 2.07g (10mmol), Pd (PPh3) 4 (0.58 g, 0.5mmol) and potassium carbonate (4.15g, 30mmol) and THF: H2O = 2: 1 solution to 100ml were dissolved was stirred for 2 hours under reflux at 80 . After this was added the organic layer was dried H2O40ml obtained by extraction three times with ethyl ether 40ml magnesium sulfate, and the solvent evaporatedObtained by purification of the residue by silica gel column chromatography to give the intermediate D-2 (1.74g, 70percent yield).(6) 1-Bromo-3-naphthylbenzene (20 g, 71 mmol) was dissolved in 250 ml of dehydrated THF. The solution was kept at -78 ° C. and 50 ml of 1.2 MR n-BuLi in hexane solution was added. After stirring for 1 hour, 25 ml of trimethyl borate was added and after stirring for 2 hours, The temperature was gradually raised. 1N HCl was added, 50 ml of methylene chloride was added and extracted, It was concentrated and dried. This operation was repeated twice to obtain 37 g of Compound 3.
