反応手順

To a solution of 5-chloro-2-{2-[4-(4-fluoro-benzyl)-(2R,5S)-2,5-dimethyl-piperazin-1-yl]-2-oxo-ethoxy}-benzaldehyde (0.10 g, 0.24 mmol) in methanol (2.5 ml) was added sarcosine methyl ester hydrochloride salt (0.10 g, 0.72 mmol) followed by sodium triacetoxyborohydride (0.155 g, 0.73 mmol). After 15 hours the solvent was removed and the resultant solid taken up in methylene chloride. After washing with pH 7 phosphate buffer (0.05 M) and saturated aqueous sodium chloride the organic layer was dried over magnesium sulfate. After filtration and concentration the title compound was isolated by chromatography on silica gel (0.051 g).
