Chemicals added in each step

Acyl group

Piperidine ring

Aniline ring

Alkyl chain

1

Forming the precursor

The aniline ring is added to the piperidine ring using aniline, an essential chemical used to make common products such as dyes and rubber.

2

Creating the intermediate

The alkyl chainis added using (2-bromoethyl)benzene, a chemical commonly found in pharmaceuticals and fragrances. This forms 4-ANPP, an immediate precursor that is tightly regulated.

3

Completion of the fentanyl structure

The final step uses propionyl chloride to add the acyl group, the last piece of the puzzle.
