Reaction Steps

A solution of 2-chloro-4-iodoaniline (25 g, 96.66 mmol) in tetrahydrofuran (100 mL) was cooled to 0° C. and then treated with acetic anhydride (50.6 g, 500 mmol). The reaction mixture was stirred at 0° C. for 10 min and then allowed to warm to 25° C. where it was stirred for 15 h. The reaction mixture was then concentrated in vacuo to remove tetrahydrofuran. The residue was crystallized from ether (50 mL) and hexanes (50 mL). The solids were collected and washed with hexanes to afford N-(2-chloro-4-iodo-phenyl)-acetamide (23.87 g, 84%) as a white crystalline solid: EI-HRMS m/e calcd for C8H7ClINO (M+) 295.1526, found 295.1532.
