A solution of 5-iodo-2-methyl-phenylamine (20.4 g, 87.6 mmol) in 200 mL of dry CH2Cl2 was cooled to 0° C. and acetic anhydride (16.5 mL, 175 mmol) was added dropwise. The mixture was heated to 50° C. for 2 h and then cooled to 22° C. The resulting white precipitate was filtered to give c (18.4 g, 76%): MS m/z=276 (M+H).
