Versuchsvorschrift

2-(4'-Aminophenyl)benzoxazole (0.14 g, 1.9 mmol) was treated with iodine monochloride (0.37 g, 2.23 mmol) in acetic acid according to the above-described general procedure for iodination. Crude product was purified by flash chromatography on silica gel using ethyl acetate-hexane (1:2) as eluent to give a brown powder (0.42 g, 65.7%), m.p. 188.0-191.2° C.
