Reaction Steps

A mixture of methyl (2-chloro-4,6-dinitrophenyl)acetate, ammonium chloride, iron powder, ethanol and water was stirred at 120° C. for 3 hours. The reaction liquid was filtered, trifluoroacetic acid was added to the filtrate, followed by stirring overnight at room temperature. The reaction liquid was concentrated under a reduced pressure, 1 M sodium hydroxide was added to the residue, and this was post-treated to obtain 6-amino-4-chloro-1,3-dihydro-2H-indol-2-one.
