反応条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 4-amino-N,N-dimethyl-2-(trifluoromethyl)benzamide (8.3 g, 23.59 mmol) in THF (100 mL) stirred under a N2 atmosphere at 20° C. was added BH3.DMS (11.20 mL, 118 mmol) dropwise. The reaction mixture was stirred at 80° C. for 2 h. To the solution was added MeOH, then concentrated in vacuo to give the crude product. The crude material was purified by silica column chromatography (DCM/MeOH=30:1). All fractions found to contain product by TLC (DCM/MeOH=10:1, Rf=0.4) were combined and concentrated to yield light yellow oil of 4-((dimethylamino)methyl)-3-(trifluoromethyl)aniline (4 g, 18.33 mmol, 78.0% yield): 1H NMR (400 MHz, CD3OD) δ 7.99 (d, J=8.0 Hz, 1H), 7.73 (s, 1H), 7.67 (d, 8.0 Hz, 1H), 4.57 (s, 2H), 2.96 (s, 6H); ES-LCMS m/z 219.2 (M+H). was added BH3 concentrated in vacuo to give the crude product The crude material was purified by silica column chromatography (DCM/MeOH=30:1) concentrated

実験手順: To a solution of N,N-dimethyl-4-nitro-2-(trifluoromethyl)benzamide (10 g, 25.2 mmol) in MeOH (100 mL) stirred under N2 at 20° C. was added Pd/C (1 g, 9.40 mmol) in one charge. The reaction mixture stirred under a H2 atmosphere at 20° C. for 12 h. The mixture was filtered, and the filtrate was concentrated in vacuo to give the desired product 4-amino-N,N-dimethyl-2-(trifluoromethyl)benzamide (8.3 g, 23.59 mmol, 94.0% yield).
