Methanol → Methyl 3-aminocinnamate

Participants

Reaction Steps

While mixing and stirring 193 g of 3-nitrocinnamic acid, 2 of methanol and 50 g of concentrated sulfuric acid, the mixture was heated under reflux for 2 hours. The reaction solution was poured into water and the crystals obtained were filtered. To a reaction solution under heat-refluxing while mixing and stirring 2 of 2-propanol, 200 ml of water, 20 g of ammonium chloride and 200 g of reduced iron, the crystals obtained above were gradually added, and the solution was further heated under reflux for one hour. The reaction solution still being hot was filtered, the filtrate was poured into 10 of water, and the crystals (methyl 3-aminocinnamate) obtained were collected by filtration. Yield: 108 g.
