実験手順: By conducting reactions and treatments in the same manner as in Example 1 using 9-fluoro-2-(4-hydroxyphenyl)-4,4a,5,6-tetrahydrobenzo[h]cinnolin-3(2H)-one and 1-methyl-2-dimethylaminoethyl chloride, there are obtained crude crystals, which are subjected to silica gel column chromatography. The crystals obtained from fractions at earlier stage are converted into fumarate, followed by recrystallization from ethanol to give 9-fluoro-2-[4-(1-methyl-2-dimethylaminoethoxy)phenyl]-4,4a,5,6-tetrahydrobenzo[h]cinnolin-3(2H)-one.fumarate.1/2 hydrate [referred to as compound of Example 11a], m.p. 176°-179° C. (decomposition). The crystals obtained from fractions at later stage are converted into fumarate, which is recrystallized from water to give 9-fluoro-2-[4-(2-dimethylaminopropoxy)phenyl]-4,4a,5,6-tetrahydrobenzo[h]cinnolin-3(2H)-one.fumarate [referred to as compound of Example 11b], m.p. 194°-195° C. are obtained crude crystals, which The crystals obtained from fractions at earlier stage followed by recrystallization from ethanol

実験手順: Powdered potassium hydroxide (96.7 g) is added to a suspension of 2-cyanophenothiazine (242 g) in methyl ethyl ketone (2.2 liters). The temperature of the mixture rises spontaneously to 24° C. and the mixture is brought to 60° C. for half an hour while stirring. The toluene solution of 2-chloro-1-dimethylaminopropane prepared above is added in the course of 30 minutes. The mixture is heated under reflux for 12 hours. After cooling, the mixture is transferred to a separating funnel and washed with distilled water (2×2 liters). The organic phase is dried over magnesium sulphate, filtered and then concentrated to dryness under reduced pressure (30 mm Hg; 4 kPa) at 50° C. to give an oil, which is diluted in ethyl ether (2 liters). The solution obtained is cooled and primed by scratching. The crystallized yellow precipitate is removed by filtration. The mother liquors are concentrated to dryness under reduced pressure (100 mm Hg; 13.3 kPa) at 30° C. to give a brown oil which is purified by chromatography on a column (height: 80 cm; diameter: 8.5 cm) of silica (0.2-0.06 mm), eluting with an 80:20 (by volume) mixture of cyclohexane and ethyl acetate and collecting 1-liter fractions. Fractions 7 to 16 are combined and concentrated to dryness at 50° C. under reduced pressure (30 mm Hg; 4 kPa) to give 10-[(2RS)-1-dimethylamino-2-propyl]-2-phenothiazinecarbonitrile (54.8 g) in the form of a brown oil. rises spontaneously to 24° C. the mixture is brought to 60° C. for half an hour above is added in the course of 30 minutes The mixture is heated under reflux for 12 hours After cooling the mixture is transferred to a separating funnel washed with distilled water (2×2 liters) The organic phase is dried over magnesium sulphate filtered concentrated to dryness under reduced pressure (30 mm Hg; 4 kPa) at 50° C. to give an oil, which The solution obtained is cooled The crystallized yellow precipitate is removed by filtration The mother liquors are concentrated to dryness under reduced pressure (100 mm Hg; 13.3 kPa) at 30° C. to give a brown oil which is purified by chromatography on a column (height: 80 cm; diameter: 8.5 cm) of silica (0.2-0.06 mm) eluting with an 80:20 (by volume) mixture of cyclohexane and ethyl acetate collecting 1-liter fractions concentrated to dryness at 50° C. under reduced pressure (30 mm Hg; 4 kPa)
