Reaction Steps

7-Iodo-1-benzofuran-5-sulfonyl chloride (10 g, 29.2 mmol; Intermediate 56) and 2-methyl aniline (3.43 mL, 32.1 mmol) were dissolved in dichloromethane (150 mL) and pyridine (3.53 mL, 43.8 mmol) was added. The solution was stirred overnight and washed with 1 M HCl (2×100 mL), dried over sodium sulfate and evaporated to give the crude solid product that was recrystallized from methanol. Yield: 5.32 g (44%) of a beige solid.
