実験手順

To a mixture of (9aS)-octahydropyrazino[2,1-c][1,4]oxazine dihydrochloride (23.28 g, 108.2 mmol) in DCM (360 mL) was added 4,6-dichloro-5-fluoro-2-methylpyrimidine (19.59 g, 108.2 mmol) and N,N-diisopropylethylamine (68 mL, 390.4 mmol). The mixture was stirred for 2 h, and the resulting solution was diluted with DCM (100 mL) and washed with saturated aq. NaHCO3 (200 mL). The aqueous phase was extracted with a fresh portion of DCM (100 mL), and this organic phase was washed with saturated aq. NaHCO3 (50 mL). The combined organic phase was dried over anhydrous Na2SO4, filtered, and concentrated in vacuo to give (9aS)-8-(6-chloro-5-fluoro-2-methyl-4-pyrimidinyl)octahydropyrazino[2,1-c][1,4]oxazine as a light yellow oil that was used without further purification. LCMS: (M+H)+: 287.1.
