Procedure

Add 2.50 g (22 mmole) of methanesulfonyl chloride dropwise to 5.06 g (15 mmole) 4-(hexafluoro-2-hydroxy-2-propyl)-aniline in 25 ml of pyridine and allow to stand overnight. Pour the reaction into H2O and extract with Et2O. Wash the Et2O with 1N HCl and extract with 1N NaOH. Acidify the NaOH and extract with Et2O. Dry, concentrate and recrystallize from Et2O-hexane to obtain 4'-(hexafluoro-2-hydroxy-2-propyl)methanesulfonanilide; m.p. 137°-139° C.
