Sulfuric Acid → tert-Butylacrylamide

Participants

Reaction Steps

To a solution of acrylonitrile (5.3 g), tert-butyl alcohol (7.4 g) and acetic acid (50 ml), cooled in an ice-bath, was added dropwise concentrated sulfuric acid (10.1 g, 97%) at a temperature below 40° C. The mixture was held at 40° C. for 1 hour and then poured into 200 g of ice water with constant stirring. The precipitate was filtered, washed with water and dried to afford N-tert-butylacrylamide (10.3 g, 82.4%); m.p. 124°-6° C.
