3,4-Dimethylaniline → N-2-heptyl-3,4-xylidine

Participants

Reaction Steps

3,4-Xylidine (24.2 grams; 0.2 mole), 2-heptanone (50.2 grams, 0.44 mole), 2-naphthalenesulfonic acid (0.9 g) and 5% of platinum on carbon (1.2 gms) were charged to a Parr reaction bottle and treated with hydrogen at 70° C. and a hydrogen pressure of 41-60 psig. The theoretical amount of hydrogen was consumed within 15 minutes. The mixture was held an additional 35 minutes, producing 43.6 g of N-2-heptyl-3,4-xylidine. The above sample analyzed 100% pure, corresponding to a yield of 99%.
