"2-methyl", that is, the methyl (-CH) group is introduced at the second position of the indole ring.
"1 - [ (4 - ethylphenyl) methyl]", where " (4 - ethylphenyl) " is a benzene ring, connected to ethyl (-CH ²) at the 4th position, and this (4 - ethylphenyl) is connected to the 1st position of the indole ring through methylene (-CH -2 -).
In summary, the chemical structure of 1- [ (4-ethylphenyl) methyl] -2-methyl-1H-indole is based on 1H-indole as the parent, with methyl substitution at 2 positions, and 4-ethylphenyl at 1 position connected by methylene.

To prepare 1 - [ (4-ethoxybenzyl) methyl] - 2-methyl-1H-indole, there are many methods for its synthesis, the following are common:
###Start with o-nitrotoluene and p-ethoxybenzaldehyde
1. ** Condensation reaction **: o-nitrotoluene undergoes a condensation reaction with p-ethoxybenzaldehyde under the catalysis of alkali to obtain the corresponding unsaturated nitro compound. This process requires careful temperature control to make the reaction mild and sufficient. The mechanism is that the alkali captures the hydrogen of o-nitrotoluene methyl to generate carbon negative ions, which then undergo nucleophilic addition with the carbonyl group of p-ethoxybenzaldehyde, and then dehydrate to form unsaturated nitro groups.
2. ** Reduction reaction **: Reduce unsaturated nitro compounds to unsaturated amines with suitable reducing agents, such as hydrogen and metal catalysts (such as palladium carbon), or iron and hydrochloric acid. This reduction step requires attention to the reaction conditions, such as hydrogen pressure, catalyst dosage, etc., to prevent excessive reduction.
3. ** Cyclization reaction **: Under acidic conditions or the action of a specific catalyst, unsaturated amines undergo intramolecular cyclization to form a 1- [ (4-ethoxybenzyl) methyl] - 2-methyl-1H-indole skeleton. Acidic conditions promote the protonation of amine groups, enhance their nucleophilicity, attack benzene ring ortho-sites, and form rings through a series of rearrangement and dehydration steps.
###Based on indole derivatives
1. ** Alkylation reaction **: Select a suitable 2-methylindole derivative and make it alkylated with electrophilic reagents such as halogenated hydrocarbons or sulfonates containing (4-ethoxybenzyl) methyl structure in the presence of a base. The function of the base is to capture the hydrogen on the nitrogen atom of the indole to generate nitrogen negative ions, so as to replace with the electrophilic reagent. Pay attention to the activity of the electrophilic reagent and the strength and dosage of the base to avoid side reactions.
2. ** Modification and improvement **: If the structure of the product still needs to be fine-tuned, further reactions can be carried out according to specific needs, such as the introduction and removal of protective groups, the conversion of functional groups, etc., to achieve the exact structure of the target product. < Br >
