YieldReaction ConditionsOperation in experiment
With sodium hydroxide; In dichloromethane; water; Reference Example 46] 1-Methylpiperazin-2-one [Show Image] An aqueous 1 N sodium hydroxide solution was added to a suspension of 1-methylpiperazin-2-one hydrochloride (19.6 g) of Reference Example 21-(3) in dichloromethane, and the resultant mixture was partitioned. Further, sodium chloride was added to the aqueous layer to saturate the layer, and then the aqueous layer was extracted with dichloromethane. The organic layers were combined and dried over anhydrous sodium sulfate. After separation by filtration, the solvent was evaporated under reduced pressure, and the title compound (5.90 g) was obtained as an oily product. ESI-MSm/z: 115(M+H)+.

YieldReaction ConditionsOperation in experiment
With caesium carbonate; 4,5-bis(diphenylphos4,5-bis(diphenylphosphino)-9,9-dimethylxanthenephino)-9,9-dimethylxanthene;palladium diacetate; In 1,4-dioxane; at 110℃; To a mixture of 6-chloro-3-nitro-2-picoline (500 mg, 2.84 mmol) and 1-methyl-piperazin-2-one hydrochloride (535 mg, 3.55 mmol) in dioxane (15 ml) were added Cs2CO3 (1215 mg, 3.69 mmol) and xantphos (25.4 mg, 0.043 mmol). The mixture was degassed with Argon for 5 min, then Pd(OAc)2 (6.37 mg, 0.028 mmol) was added. The light brown suspension was heated up to 1 100C and stirred for 18h. The reaction mixture was concentrated then diluted in EtOAc/NaHCO3 aq. sat. soP. The aqueous layer was extracted twice with EtOAc. The combined organics were washed with brine, dried (Na2SO4) and after filtration, the solvent was removed under reduced pressure and the crude product was dried under high vacuum (500C). Purification was done by chromatography on silica gel (eluting with DCM / MeOH; 99/1 then 98/2) to obtain the title compound as a pink solid (347mg). (HPLC: tR 5.319 min (Method B); M+H = 251.2 MS-ES)
