9‐[(N‐Methyl‐3′‐piperidyl)‐methyl]‐thioxanthene‐10‐oxide (I) on treatment with boiling concentrated hydrochloric acid gives mainly 9‐[(N‐methyl‐3′‐piperidyl)‐methylene]‐thioxanthene (IV) together with small amounts of 9‐[(N‐methyl‐3′‐piperidyl)‐chloro‐methylene]‐thioxanthene(II), 9‐hydroxy‐9‐[(N‐methyl‐3′‐piperidyl)‐methyl]‐thioxanthene (III) and 9‐[(N‐methyl‐3′‐piperidyl)‐methyl]‐thioxanthene (V). Treatment of I with acetic anhydride yields only IV.
