A new method for the synthesis of bisacodyl 1 is described. The key step involves migration of 2-pyridacyl group of phenyl pyridine-2-carboxylate 4 in AlCl3 at 160 °C to yield the intermediate 4-hydroxyphenyl (2-pyridyl) ketone 5a. The reaction of 5a with phenol using H3PO 4 gives 1. This method has advantage over the existing literature methods because easily available pyridine-2-carboxylic acid is used as a starting material instead of the less stable pyridine-2-carboxaldehyde.
