Reaction Steps

To a solution of 2,2,2-trifluoro-N-[(1R)-1-methyl-2-phenylethyl]acetamide (3.75 g) in acetic acid (32 ml)—water (6.5 ml)—sulfuric acid (0.97 ml) were added iodine (1.65 g) and periodic acid dihydrate (740 mg) at room temperature, and the mixture was heated to 60-80° C. for 5 hours. After being allowed to cool to room temperature, the mixture was partitioned between hexane/ethyl acetate and water. The organic layer was separated, washed successively with water, sodium sulfite solution, water and brine, dried over magnesium sulfate, and filtered. The filtrate was concentrated and the residue was recrystallized from diisopropyl ether (44 ml) to give 2,2,2-trifluoro-N-[(1R)-2-(4-iodophenyl)-1-methylethyl]acetamide (2.15 g) as a colorless needle.
