B-(2-Aminophenyl)boronic acid Use and Manufacturing
The reaction flask was charged with compound II (8 g, 47.9 mmol), ethanol (40 ml) and water (60 ml) under a 50 ° C oil bath. Under nitrogen protection, iron powder (16 g) and concentrated hydrochloric acid (0.5 ml) were added and incubated for 3 hr. After completion of the reaction, ethanol (80 ml) was added to the reaction mixture, and the mixture was filtered through celite to obtain a light brown syrup. Concentrated under reduced pressure as a brown solid, recrystallized from 50percent ethanol, filtered and dried to give a pale gray color compound (5.5 g) in 83percent yield.A mixture of 84A (1.0 g, 6 mmol) and 10percent Pd/C (50 mg) in EtOH (50 mL) was hydrogenated in a Paar shaker at 1 bar for 8 hours. The mixture was filtered through a pad of celite and the filtrate was concentrated. The resulting residue was triturated with hexanes and the resulting solid was filtered to afford 84B (0.4g, 50percent).(i)(i) The 1.10g to iodine aniline (5mmol), 1.40g connecting boric acid pinacone ester (5.5mmol), 1.45g acetic acid potassium (15mmol) and PdCl
