SUMMARY:

The COVID-19 pandemic has affected millions of people in the entire world and caused a shortage of several drugs, including propofol. Therefore, several protocols for propofol synthesis have been published in recent years. Herein, we present a process starting from paracetamol, a very common and abundant active pharmaceutical ingredient. Since the first three steps (Friedel–Crafts double alkylation, acetyl deprotection, and diazotization) are done in acidic media, a one-pot approach was developed. Furthermore, we observed that the extraction of the final product can be simplified by steam-distillation, leading to propofol in 47% isolated yield with high purity. This presented process could be an example of active pharmaceutical ingredient reuse since similar results were observed with commercial paracetamol tablets (with excipients) regardless of expiration date.
