Reaction Steps
lodination of 4-aminobenzonitrile 30 with ICI produces 4-amino-3-iodobenzonitrile 31. Acetylatation of 4-amino-3-iodobenzonitrile 31 results in compound 32, which can be reduced with Raney nickel to form 4-acetamido-3-iodobenzaldehyde 33. Reaction of compound 33 with thiosemicarbazide yields 4-acetamido-3-iodobenzaldehyde thiosemicarbazone 34, as illustrated below.
