Versuchsvorschrift
Sodium hydride (930 mg, 23.3 mmol of 60% oil dispersion) was washed with hexanes under a nitrogen atmosphere and suspended in 100 mL of anhydrous THF. Thiomorpholin-3-one (1.0 g, 8.55 mmol) was added, followed immediately by 2-(4-methylpiperazin-1-yl)-benzaldehyde (1.58 g., 7.75 mmol). The reaction was then heated to reflux overnight, cooled to room temperature and concentrated in vacuo. The residue was dissolved in methylene chloride and washed with aqueous ammonium chloride (NH4Cl) and saturated brine and then dried with MgSO4. Purification using flash chromatography gave 2-{hydroxy-[2-(4-methylpiperazin-1-yl)phenyl]-methyl}-thiomorpholin-3-one as a white solid, m.p. 137-139° C. Mass spectrum 322 (M+1).
