The phosphonic acid analog of the NSAID Diclofenac was efficiently synthesized via an Arbuzovreaction between 2-(2,6-dichloroanilino)benzyl alcohol and trimethyl phosphite followed by TMSBr promoted dealkylation. Seven related phosphonic acids were synthesized using the same novel acid-catalyzed Arbuzovreaction as the key step.
