実験手順

4-Chloro-3-iodoaniline (2.5 g, 9.88 mmol) was used in Procedure E with 5-acetylthiophene-2-carboxylic acid (1.85 g, 10.8 mmol) at 23° C. for 2 hours. The crude material was purified by silica gel chromatography (20-100% ethyl acetate/hexanes) to yield 5-Acetyl-N-(4-chloro-3-iodophenyl)thiophene-2-carboxamide as a yellow solid.

後処理
