Synthesis of 6-Ethyloctahydro-1H-pyrrolo[3,4-b]pyridine

There are several synthetic routes to 6-Ethyloctahydro-1H-pyrrolo[3,4-b]pyridine, each with its own advantages and disadvantages.
Here are some of the most common methods:

1. Pyrrole Synthesis

The pyrrole synthesis route to E-Phanthrene is one of the most straightforward methods.
The synthesis involves the reaction of acetaldehyde diethyl acetal with sodium hydroxide in the presence of a solvent such as dimethylformamide (DMF).
The reaction leads to the formation of the corresponding acetal, which can then be hydrolyzed to pyrrole using hydrochloric acid.
Finally, the pyrrole is treated with chloroethyl chloride to introduce the vinyl group, resulting in E-Phanthrene.

2. Methylation Pyrrole Synthesis

Another method for the synthesis of E-Phanthrene is the methylation pyrrole synthesis route.
This method involves the reaction of pyrrole with methyl iodide in the presence of a solvent such as ether or hexane.
The reaction leads to the formation of methyl pyrrole, which is then treated with sodium hydroxide to convert it to the corresponding sodium salt.
Finally, the sodium salt is reduced with hydrogen in the presence of a catalyst such as palladium on barium sulfate to yield E-Phanthrene.

3. Electrophilic Halogenation

E-Phanthrene can also be synthesized by electrophilic halogenation of pyridine using chloroformic acid.
The reaction involves the formation of a phosphoric acid intermediate, which undergoes an intramolecular electrophilic substitution reaction to yield E-Phanthrene.
