Tryptamine Synthesis from L-Tryptophan via cyclohexanol with catalyst 2-cyclohexen-1-one

Nexus - 17-10-2013 at 19:38

Im about to commit to buying the chemicals for the following synthesis found on Rhodium.

20 grams of L-Tryptophan was dissolved in 150 ml cyclohexanol
containing 1.5 ml of 2-cyclohexen-1-one, and the temp of the solution was held at 154°C for 1.5 hours. The tryptamine was isolated as the HCl salt, mp 256°C. Yield 92.3%.

-as previously mentioned, the HCl needs to be added as a gas (dry). Im guessing this causes the precipitation of Tryptamine HCl?

Is there any further commentariers that can be added to help me through this decarboxylation?
