Reaction Steps
To a solution of 2,4,6-trifluoronitrobenzene (2.58 g, 0.0145 mol) in THF (20.0 ml) was added a solution of N,N-dimethylamine in THF (8.5 mL of 2M soln) and stirred for 45 min at 0° C. It was then stirred at room temperature for 30 min and concentrated to dryness. The resulting material was dissolved in EtOH (25 mL), added Pd/C (10%, 0.6 g) and hydrogenated at 50 psi for 4 h. The catalyst was removed by filtration, and the filtrate was concentrated to dryness under reduced pressure. The residue was partitioned between sod. bicarbonate (10%, 25 mL) and EtOAc (30 mL). The organic phase was washed with water, dried (Na2SO4), and concentrated to dryness to afford the title compound (1.3 g, 50%) as a dark colored solid: 1H NMR (CDCl3/400 MHz) δ6.52 (m, 2H), 3.64 (br, 2H), and 2.65 (s, 6H); ES-HRMS m/z 172.0772 (M+C8H10N2F2 requires 172.0810).
