Reaction Steps

(2-Amino-6-bromo-benzyl)-methyl-carbamic acid tert-butyl ester (371 mg) was dissolved in 50 ml ethanol. To this solution was added 2M ethanolic hydrochloride acid solution (10 ml). The reaction mixture was heated at 100° C. for 30 minutes, at which time the deprotection was completed. The solution was allowed to cool to room temperature and poured into the mixture of saturated NaHCO3 solution and ethyl acetate. The aqueous layer was extracted with EtOAc three times and the organic fractions were concentrated to give 3-bromo-2-methylaminomethyl-phenylamine as a brown oil (1.938 g, 76%). MS: (M+H)+217.1.
