1,2-Dimethoxyethane → HCID 54217329, compound

Participants

Reaction Steps

Methyl 3-bromobenzoate (458 mg, 2 mmol), 1-styreneboronic acid pinacoyl ester (484 mg, 2.1 mmol), Na2CO3 (222 mg, 2.1 mmol), tetrakis(triphenylphosphino)palladium (116 mg, 0.1 mmol), water (4 mL) and 1,2-dimethoxyethane (6 mL) were stirred with reflux conditions for one hour, under nitrogen. The reaction mixture was diluted with water and was extracted three times with EtOAc. The organic layers were combined, washed with water and then brine, dried over MgSO4 and concentrated. The product was purified by trituration with Et2O. White crystals were obtained (393 mg, 82%). NMR 1H (ppm, CDCl3): 8.19 (t, J4=1.6 Hz, 1H), 7.91 (dt, J3=7.7 Hz, J4=1.3 Hz, 1H), 7.67 (d, J3=7.8 Hz, 1H), 7.52 (d, J3=7.3 Hz, 2H), 7.42 (t, J3=7.9 Hz, 1H), 7.36 (t, J3=7.4 Hz, 2H), 7.30-7.26 (m, 1H), 7.19 (d, J3=16.3 Hz, 1H), 7.11 (d, J3=16.4 Hz, 1H), 3.06 (s, 3H).
