5-AMINO-3-BROMOBENZONITRILE Use and Manufacturing
A flask containing 3-bromo-5-nitrobenzonitrile (3 g, 13.2 mmol) in MeOH (100mL) was cooled in an ice-water bath. To the solution was added zinc (3.46 g, 52.9 mmol)and acetic acid (6.05 mL, 106 mmol). After a minute, an exotherm was observed. After 2 h, the reaction mixture was filtered through celite and the filtrate concentrated. The resulting residue was purified by silica gel chromatography using 0 to 50percent ethyl acetate in hexanes. The product containing fractions were combined and evaporated to give 3-amino-5-bromobenzonitrile (2.1 g, 81percent): HPLC: RT=0.80 mm (Waters Acquity UPLC BEH C18 1.7 um 2.0 x 50 mm, CH3CN/H20/0.05percentTFA, 1 mm gradient, wavelength=254nm); MS (ES): m/z= 196.9/198.9 79Br/8’Br [M+1f ‘H NMR (DMSOd6) & 7.06-7.09 (m, 1H), 7.04 (t, J2.0 Hz, 1H), 6.87 (dd, J=2.1, 1.4 Hz, 1H), 5.91 (s, 2H).To a stirring solution of 845 mg (3.72 mmol) of 3-bromo-5-nitrobenzonitrile in 5 rnL of THF and 5 rnL of EtOH was added 4.2 g (18.6 mmol) of SnCl
