Versuchsvorschrift
A solution of D series 2-(2-cyano-10-phenothiazinyl)-propyl methanesulphonate (6.8 g) in toluene (80 cc) and (2RS)-2-methylpyrrolidine (3.5 cc) is heated with stirring at 100° C. for 48 hours. After cooling to 25° C., the mixture is transferred into a separating funnel where it is washed with distilled water (2×200 cc) and brine (50 cc). The organic phase is dried over magnesium sulphate and filtered, and the filtrate is concentrated to dryness under reduced pressure (30 mm Hg; 4 kPa) to give a residue which is purified by chromatography on a column (height: 35 cm; diameter: 3.2 cm) of silica (0.2-0.06 mm), eluting with a mixture of cyclohexane and ethyl acetate 70-30 (by volume) (1 liter), collecting fractions of 60 cc. Fractions 11 to 14 are pooled and concentrated to dryness under reduced pressure (30 mm Hg; 4 kPa) to give 10-{1-[(2RS)-2-methyl-1-pyrrolidinyl]-2-propyl}-2-phenothiazinecarbonitrile, D series (0.5 g), in the form of a yellow oil.
