Reaction Steps

5-Fluoro-2-nitrophenylamine (1.0 eq) and morpholine (3.0 eq) were dissolved in NMP and heated at 100° C. for 1 hour. The solution was cooled to room temperature and diluted with water. The resulting precipitate was filtered and dried under vacuum to yield 5-morpholin-4-yl-2-nitrophenylamine. The resulting solid was recrystallized from EtOH to afford pure product as a bright yellow solid. LC/MS m/z 224.1 (MH+), Rt 1.89 minutes.
