実験手順: The general procedure 1 was then followed using 1-(3-chloropropyl)-4-methylpiperazine (12.5 mmol, 2.2 g), ethyl-2-(1H-indol-3-yl)-2-oxoacetate (10 mmol, 2.17 g) and K2CO3 (10.8 mmol, 1.5 g). The purification was achieved by column chromatography (petrolether:ethylacetate:diethylamine 5:5:1) to yield ethyl-2-{1-[3-(4-methylpiperazin-1-yl)propyl]-1H-indol-3-yl}-2-oxoacetate (5.3 mmol, 42%).

実験手順: 12 grams of N,N-dimethyl-7-fluoro-phenothiazine-2-sulphonamide were dissolved in 50 milliliters of dry dimethylformamide, 1.9 grams of 50% sodium hydride in oil added and the mixture stirred for 1 hour. 7.2 grams of 1-(3-chloropropyl)-4-methylpiperazine were then added and the mixture heated for two hours on a steam bath. Then the mixture was poured onto crushed ice, the resulting mixture extracted with ether, the ether phase washed, dried over anhydrous magnesium sulphate and the ether evaporated. 13 grams of 2-dimethylsulphamoyl-7-fluoro-10-(3-(4-methylpiperazin-1-yl)propyl)phenothiazine was thus obtained as a yellow oil. The dimaleate was made from an ethanol solution of the base and melted at 166°-169° Centigrade. the mixture heated for two hours on a steam bath Then the mixture was poured onto crushed ice the resulting mixture extracted with ether the ether phase washed dried over anhydrous magnesium sulphate the ether evaporated

実験手順: N-Methyl piperazine (0.2 mol) and 1-bromo-3-chloropropane (0.1 mol) in toluene (100 mL) were heated at 80° C. for 3 hr. The precipitate was collected and the remaining filtrate extracted with HCl (1N, 2×50 mL). The aqueous layer was made basic with NaOH (1N) and extracted with ether (3×100 mL). The combined ether layers were washed with water, dried (MgSO4), filtered and evaporated to afford product as a pale yellow oil. The precipitate was collected the remaining filtrate extracted with HCl (1N, 2×50 mL) extracted with ether (3×100 mL) The combined ether layers were washed with water dried (MgSO4) filtered evaporated to afford product as a pale yellow oil
