Reaction Steps
To a mixture of N-((2-(methylthio)benzo[d]thiazol-6-yl)methyl)-3-nitro-5-(trifluoromethyl)pyridin-2-amine (0.97 g, 2.42 mmol), HOAc (4 mL), and MeOH (4 mL) in DCM (30 mL) cooled in ice-water bath was slowly added zinc dust (1.6 g, 24.2 mmol). The reaction mixture was stirred at 0° C. for 2 h. The mixture was filtered and the filtrate was diluted with DCM and then washed with water and aq NaHCO3. The organic layer was dried over Na2SO4, filtered and concentrated under reduced pressure to afford N2-((2-(methylthio)benzo[d]thiazol-6-yl)methyl)-5-(trifluoromethyl)pyridine-2,3-diamine (0.89 g, 100%). 1H NMR (300 MHz, DMSO-d6) δ 8.05 (s, 1H), 7.82 (d, J=8.4 Hz, 1H), 7.77 (s, 1H), 7.44-7.41 (m, 1H), 7.03 (d, J=1.8 Hz, 1H), 4.84 (br s, 1H), 4.78 (d, J=5.1 Hz, 2H), 3.29 (br s, 2H), 2.79 (s, 3H). LCMS (ESI) m/z 371 (M+H)+.
