Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In the same manner, 4-(3,4-dichlorobenzyl)-thiomorpholin-3-one was prepared in 89% yield from 3,4-dichlorobenzyl bromide and thiomorpholin-3-one as a white solid.

Conditions: temp:192.51; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of thiomorpholin-3-one (500 mg, 4.27 mmol), 4-trifluoromethyl-1-iodobenzene (1.25 mL, 8.5 mmol) and copper metal (814 mg, 12.8 mmol) was heated in a sealed glass tube at 185-200° C. for 18 hours. The residue was then purified by flash chromatography to give 260 mg of the title product as a white solid. The residue was then purified by flash chromatography

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Under a nitrogen atmosphere in a flame-dried flask, sodium hydride (72 mg, 1.79 mmol, 60% oil dispersion) was washed with hexanes and then treated with 6 mL of anhydrous DMF, and cooled to 0° C. Thiomorpholin-3-one (200 mg, 1.71 mmol) was added in one portion with stirring. After gas evolution had stopped (ca. 30 min), 4-iodo-1,2-dichlorobenzene (700 mg, 2.56 mmol) was added, followed after 5 minutes by copper (I) bromide (490 mg, 3.42 mmol). After heating at 75° C. overnight, the mixture was partitioned between ethyl acetate and 1N lithium chloride, filtered through diatomaceous earth and combined with additional ethyl acetate washes of the diatomaceous earth filter cake. The organic layers were washed with additional 1N lithium chloride, brine (saturated sodium chloride) and dried over calcium sulfate (CaSO4). Concentration in vacuo gave 363 mg of light brown oil which was flash chromatographed (30-50% ethyl acetate in hexanes) to give a white solid, 108 mg. was added After heating at 75° C. overnight the mixture was partitioned between ethyl acetate and 1N lithium chloride filtered through diatomaceous earth filter cake The organic layers were washed with additional 1N lithium chloride, brine (saturated sodium chloride) dried over calcium sulfate (CaSO4) Concentration in vacuo

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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). The reaction was then heated to reflux overnight concentrated in vacuo The residue was dissolved in methylene chloride washed with aqueous ammonium chloride (NH4Cl) and saturated brine dried with MgSO4 Purification
