Sodium Carbonate → 4-Amino-n-sec-butyl-n-ethyl-3-toluidine

Participants

Reaction Steps

A suspension of iron powder (8.34 g) in methanol (60 ml) and hydrochloric acid (20 ml) was stirred at reflux for 15 mins. A solution of the product from Stage 1d (11 g) in methanol (60 ml) was added dropwise over 15 mins and refluxing continued for 3 hours. Sodium carbonate was added until no soluble iron remained and the solution was alkaline to Brilliant Yellow paper. The hot reaction mixture was filtered and the solvent removed under reduced pressure to give the product as a brown oil.
