- Product Name:Melatonine
- CAS Number:73-31-4
- Molecular formula:C13H16N2O2
- Molecular Weight:232.28
Yield:73-31-4 98.6%
Reaction Conditions:
at 305; for 4 h;Temperature;
Steps:
1.5; 2.5; 3.5; 4.5; 5.5
(5) 50g 5-methoxytryptamine and 65g acetic anhydride were added to the reactor, stirred at 305°C for 4h, and the reaction progress was monitored by TLC; after the reaction, 300mL of water was added to the reactor, and then 20% sodium carbonate was used The pH value of the solution is adjusted to 6.8, and a solid melatonin appears. The solid melatonin is collected by filtration, and the collected solid melatonin is dried in an oven at 60° C. to obtain the final product melatonin. The yield was 98.6% and the purity was 99.3%.
