Dehydration of 9.2 g of p-aminophenylethanol (Chem. Abs., vol. 59:3797f) was done by heating with 8.8 g of KOH in the flame of a Bunsen burner under a nitrogen atmosphere (about 6 mm pressure). The product was collected by cooling with a Dry Ice-acetone bath. The solution was extracted with ether, dried over KOH and filtered. Evaporation of the ether gave p-aminostyrene, which was characterized by IR and NMR; the yield was 6.4 g.
