Reaction Steps
To a solution of tert-butyl 2-chloro-4-nitro-benzoate (2.05 g, 7.98 mmol) in ethanol 12 mL) and ethyl acetate (108 mL) was added platinum on activated charcoal (5%, 295 mg), and the mixture was stirred under at room temperature under a hydrogen atmosphere (1 bar). After filtration through a pad of diatomaceous earth, the filtrate was evaporated to afford tert-butyl 4-amino-2-chlorobenzoate (1.75 g, 96%). Orange solid, MS (EI)=227.2 (M+).
