Reaction Steps
To a stirred mixture of (5-fluoro-2-(methylthio)benzo[d]thiazol-6-yl)methanamine (128 mg, 0.6 mmol) and DIEA (195 μL, 1.2 mmol) at 0° C. under argon was added 2-chloro-3-nitropyridine (98 mg, 0.7 mmol) in one portion. The mixture was stirred at rt for 18 h and then concentrated under reduced pressure. The residue was purified by silica gel flash chromatography eluting with a gradient of 100% hexanes to 50% EtOAc in hexanes to afford N-((5-fluoro-2-(methylthio)benzo[d]thiazol-6-yl)methyl)-3-nitropyridin-2-amine (165 mg, 84%) as a yellow oil. LCMS (ESI) m/z 351 (M+H)+.
