Reaction Conditions

Reaction Steps

A solution of N-trifluoroacetyl-1-(3-methoxyphenyl)-2-propylamine (4.29 g, 15.7 mmol) in methanol (100 mL) was cooled to −78° C. and treated with CaCO3 (3.17 g, 31.4 mmol), followed by a solution of ICl (6.37 g, 39.3 mmol) in methanol (50 mL). The reaction was allowed to warm to 20° C. while stirring overnight. The product mixture was filtered, concentrated, dissolved in EtOAc (200 mL), washed twice with 5% aqueous sodium bisulfite (100 mL), once with brine (100 mL), dried with Na2SO4 and concentrated to give 6.72 g of a white solid powder. MS calculated for C12H13F31NO2+H: 388, observed: 388.
