Participants

Reaction Steps

Charge a 5 L, 3 neck flask equipped with a mantle, stirrer, condenser, with 708 grams (5M) 3-Iodo-2-Methyl Aniline, followed by 700 ml glacial acetic acid. Add in a stream of 520 grams (5.1M) acetic anhydride and allow the solution to come to a gentle reflux for an hour. The solution is allowed to cool and poured in a stream in a large container of 8 L ice water. The product will crystallize immediately and is filtered and squeezed under vacuum and air-dried. Yield was 900 grams (Theoretical yield=918 g).
