1,2-BENZENEDIAMINE, 4-BROMO-N2-METHYL- Use and Manufacturing
A solution of 12a (350 mg, 1.51 mmol), zinc (495 mg, 7.57 mmol), and NHThe NHStep B(2-amino-5-bromophenyl)methylamine [00303] To a bright yellow solution of 5-bromo-N-methyl-2-nitroaniline (1.56 g, 6.75 mmol) in EtOH (100 mL) was added dropwise a solution of sodium dithionate (8.35 g, 40.5 mmol) in HPart B:To compound 229 (5.40 g, 23.4 mmol) in ethanol (200 ml_) was added tin (II) chloride (22.2 g, 117 mmol). The resulting solution was stirred at 7OExample 47 4- (Benzyloxy) -1- (2-ethyl-l-methyl-lH-benzimidazol-6- yl) pyridin-2 (1H) -one A) 6-Bromo-2-ethyl-l-methy1-lH-benzimidazole A mixture of 5-bromo-N-methyl-2-nitroaniline (10 g) , zinc (14.15 g), NHTo I-36.1 (5.27 g, 22.81 mmol) in ethyl acetate is added platinum on carbon (550 mg) and stirred under hydrogen (5 bar) at r.t. for 4 h. The reaction mixture is filtered through a pad of celite and concentrated. The crude product is used without further purification for the next step. Yield 96percent.
