Procedure
A mixture of 3-nitro-2,4-difluoro-benzonitrile (500 mg, 2.72 mmol), Pd/C (200 mg), conc HCl (1.50 mL) and MeOH (25 mL) is stirred at rt overnight under a hydrogen atmosphere (3 bar). The catalyst is removed by filtration, the filtrate is concentrated and evaporated twice from EtOH to give the sub-title compound as HCl salt.
