Procedure

To a solution of (2-nitro-phenyl)-(2,2,2-trifluoro-ethyl)-amine (2.16 g, 9.8 mmol) in THF (6 mL) and MeOH (24 mL) at 0° C. was added ammonium formate (2.47 g, 39.2 mmol). The resulting mixture was purged with nitrogen, then 10% Pd/C (57 mg) was added. The ice bath was removed and the resulting mixture was stirred at room temperature for 5 h. The resulting mixture was filtered over CELITE®, washing with EtOAc. Removal of the solvent in vacuo yielded N-(2,2,2-trifluoro-ethyl)-benzene-1,2-diamine, which was used in the next step without further purification. MS 191 (M+1)+
