反応条件: temp:0.00; pressure:0.00; stir:

反応条件: temp:110.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 2-Fluorobenzonitrile (1.21 g, 1.00 mmol) was dissolved in acetonitrile (50 ml), and morpholine (33 ml, 377 mmol) was added thereto followed by stirring at 110° C. for 2 nights. After the reaction was completed, the reaction mixture was concentrated to give oily substances which were then purified by silica gel chromatography (eluent: chloroform) to give the title compound (1.80 g, 95%) as oily substances. the reaction mixture was concentrated to give oily substances which were then purified by silica gel chromatography (eluent: chloroform)

反応条件: temp:-78.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 5.39 ml (9.69 mmol) of a 1.8 M lithium diisopropylamide THF solution was diluted with 10 ml of THF. Thereafter, 5 ml of a THF solution containing 383 mg (1.94 mmol) of the 5-chloro-2,N,N-trimethylbenzamide prepared in Step A of Example 80 was added dropwise to the diluted solution at −78° C. Thereafter, 5 ml of a THF solution containing 438 mg (2.33 mmol) of 2-(4-morpholino)benzonitrile was further added to the above mixture, and the obtained mixture was then stirred at −78° C. for 30 minutes. Thereafter, a saturated ammonium chloride aqueous solution was added to the reaction solution, and the mixture was then extracted with ethyl acetate. The extract was washed with a saturated saline solution, and was then dried over anhydrous sodium sulfate. The resultant was concentrated under reduced pressure. The obtained yellow oily product was crystallized from hexane/ethyl acetate (3:1), so as to obtain 575 mg (87%) of 7-chloro-3-(2-morpholin-4-ylphenyl)-2H-isoquinolin-1-one in the form of a colorless crystal. was added dropwise to the diluted solution at −78° C was further added to the above mixture the mixture was then extracted with ethyl acetate The extract was washed with a saturated saline solution was then dried over anhydrous sodium sulfate The resultant was concentrated under reduced pressure The obtained yellow oily product was crystallized from hexane/ethyl acetate (3:1)

実験手順: A 1.8 M lithium diisopropylamide THF solution (5.39 ml, 9.69 mmol) was diluted with THF (10 ml). To the diluted solution, a solution obtained by dissolving the 5-chloro-2,N,N-trimethylbenzamide (383 mg, 1.94 mmol) prepared in step A in THF (5 ml) was added dropwise at −78° C. A solution obtained by dissolving 2-(4-morpholino)benzonitrile (438 mg, 2.33 mmol) in THF (5 ml) was further added to the mixture. The obtained mixture was stirred at −78° C. for 30 minutes.

実験手順: To a stirred solution of 2-(4-morpholino)benzonitrile (3.76 g, 20 mmol) and N-methylhydroxylamine hydrochloride (3.34 g, 40.0 mmol) in 1:1 water/ethanol (100 mL) was added sodium carbonate (2.12 g, 20 mmol) and the resulting mixture stirred at 90° C. overnight. After cooling and concentrating, the resulting residue was suspended in MeOH/CHCl3 (1:9). The insoluble solids were removed by filtration and concentration of the mother liquor gave the title product as an amber oil (3.8 g) that was carried on without further purification. LCMS calcd for C12H18N3O2 (M+H): 236.13; found: 236.31. After cooling concentrating The insoluble solids were removed by filtration and concentration of the mother liquor
