Procedure

To a slurry of optically active 7-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)-phenyl]-[1,4]oxazepane hydrochloride (0.12 g, 0.41 mmol) and 2-chloro-3-methyl-6-(pyrimidin-4-yl)-3H-pyrimidin-4-one (0.09 g, 0.38 mmol) was added triethylamine (0.21 mL, 1.5 mmol) at room temperature. The mixture was stirred for 20 hours and poured into water. Extractive workup with chloroform was performed and the organic phase was dried over sodium sulfate. Concentration followed by purification of the residue by flash column chromatography on silica gel (chloroform/methanol=100/0 to 90/10 as eluants) yielded (+)-2-{7-[4-(5-methyl-[1,2,4]-oxadiazole-3-yl)phenyl]-[1,4]-oxazepane-4-yl}-3-methyl-6-pyrimidin-4-yl-3H-pyrimidin-4-one (A100) (0.09 g, 0.19 mmol, 50%) as yellowish solid.
