PROCEDURE

实验过程

To 5.4 g (20 mmole) N-methyl-4-(hexafluoro-2-hydroxy-2-propyl)aniline in 50 ml pyridine add 4.3 g (30 mmole) dimethylsulfamoyl chloride. Stir 16 hours, pour onto water, acidify and extract with Et2O. Wash with 1N NaOH, acidify the aqueous layer, and extract with Et2O. Dry, concentrate and recrystallize first from CCl4, and then from Et2O-hexane to obtain the product; m.p. 63°-65° C.
