実験手順: A mixture of 60.24 g (0.350 mole) of [(2-chloroethyl)thio]benzene, 84 g (0.72 mole) of N,N-diethylethylenediamine, and 80.0 g (0.75 mole) of sodium carbonate in 1.5 liters of acetonitrile was refluxed for 16 hr. The solvent was removed in vacuo, and the residue was partitioned between methylene chloride and dilute sodium hydroxide. The methylene chloride solution was dried over sodium sulfate, and the solvent was removed in vacuo to give an oil. This was dissolved in 800 ml of methanol. A solution of approximately 2 equivalents of maleic acid in methanol was added followed by the addition of anhydrous diethyl ether until the solution became slightly cloudy. A white solid precipitated at -5° C. to give 73.15 g (43.2%) of title compound, a white crystalline solid, mp 131°-133° C. was refluxed for 16 hr The solvent was removed in vacuo the residue was partitioned between methylene chloride and dilute sodium hydroxide The methylene chloride solution was dried over sodium sulfate the solvent was removed in vacuo to give an oil A white solid precipitated at -5° C.

実験手順: 3.44 g (20.0 mmol) (2-chloroethyl)(phenyl)sulfane and 5.53 g (40.0 mmol) potassium carbonate were added to a solution of 1.56 g (10.0 mmol) 2-mercapto-3-nitropyridine in DMF (30 ml) and heated for 4 h at 60° C. Then the mixture was diluted with EE and washed with brine. The organic phase was separated off, dried over Na2SO4, filtered and concentrated to small volume under vacuum. Column chromatography (hexane/EE 9:1) of the residue yielded 1.93 g (6.6 mmol, 66%) 3-nitro-2-(2-phenylsulfanyl-ethylsulfanyl)pyridine. Then the mixture was diluted with EE washed with brine The organic phase was separated off dried over Na2SO4 filtered concentrated to small volume under vacuum

実験手順: A solution of 25 g (0.145 mole) of 2-chloroethyl phenyl sulfide and 1 g (0.006 mole) of potassium iodide in 500 ml of isopropylamine was heated in a bomb at 120° C. for 24 hr. The solvent was removed in vacuo, and the residue was partitioned between methylene chloride and dilute sodium hydroxide. The methylene chloride solution was extracted with dilute sulfuric acid. The acidic extract was made basic with 50% sodium hydroxide, and the basic solution was extracted with methylene chloride. The methylene chloride solution was dried over magnesium sulfate and the solvent was removed in vacuo to given an oil. This was converted to the hydrochloride salt, and the salt was recrystallized from methanol-ether to give 25.77 g (76.9%) of white crystalline solid, m.p. 124.5°-125.5° C. The solvent was removed in vacuo the residue was partitioned between methylene chloride and dilute sodium hydroxide The methylene chloride solution was extracted with dilute sulfuric acid The acidic extract the basic solution was extracted with methylene chloride The methylene chloride solution was dried over magnesium sulfate the solvent was removed in vacuo the salt was recrystallized from methanol-ether

実験手順: Benzenethiol (15.0 g, 0.136 mol) was added to the solution of sodium ethoxide (0.20 mol) in 200 ml of anhydrous ethanol, and the mixture was stirred at room temperature for 15 minutes and then added to the solution of 1-bromo-2-chloroethane in 100 ml of ethanol. The resultant mixture was stirred at room temperature for 3 hours and poured into 300 ml of water. The mixture was extracted three times with ether and the combined organic layer was dried over magnesium sulfate. After removal of the solvent, the compound was purified by flash chromatography using heptane/ethyl acetate (100 to 97/3) as eluent in a yield of 74%. The mixture was extracted three times with ether the combined organic layer was dried over magnesium sulfate After removal of the solvent the compound was purified by flash chromatography
