The synthesis of a newseries of 4‐aryl‐3‐chloro‐2‐oxo‐N‐[3‐(10H‐phenothiazin‐10‐yl)propyl]azetidine‐1‐carboxamides, 4a–4m, is described. Phenothiazine on reaction with Cl(CH2)3Br at room temperature gave 10‐(3‐chloropropyl)‐10H‐phenothiazine (1), and the latter reacted with urea to yield 1‐[3‐(10H‐phenothiazin‐10‐yl)propyl]urea (2). Further reaction of 2 with several substituted aromatic aldehydes
