Versuchsvorschrift

A solution of 2-bromophenothiazine (41.72 g., 0.05 mole) in 200 ml. of dry toluene was added to a stirred solution of 9.6 g. (0.15 mole) of n-butyllithium in 100 ml. of dry toluene. The stirred solution was warmed for about 2.0 hours at 45°-50° C. and then 31.5 g. (0.20 mole) of bromopropylchloride in 50 ml. of dry toluene was added. The mixture was refluxed for 15 hours. The cooled reaction mixture was washed with water, dried over sodium sulfate and the dried solution concentrated at reduced pressure. The residual oil was distilled to give the product, 2-bromo-10-(3-chloropropyl)phenothiazine.
