Sulfuric Acid → Propanamide, 2-(dimethylamino)-2-methyl-

Participants

Reaction Conditions

Reaction Steps

Conc. Sulphuric acid (8 ml.) was added to 2-dimethylamino-2-methyl-propionitrile (2 g.), and was heated to 90° C. and allowed to stand for five mins. The reaction mixture was added to ice cold water (100 ml.), barium hydroxide (32 g.) was added to neutralise the acid and the mixture was filtered (hyflo). The filtrate was evaporated under reduced pressure to give a solid residue which was crystallised from light petroleum (80°-100° C.) to give 2-dimethylamino-2-methylpropionamide (1 g. 45%) m.p. 109°-111° C.
