反応条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Methyl 3,5-dibromo-4-hydroxybenzoate (1000 mg, 3.23 mmol) was dissolved in THF (16 mL) and N-methylmorpholine (0.709 mL, 6.45 mmol) was added. The mixture was cooled to 0° C. and phenyl chlorodithioformate (0.549 mL, 3.87 mmol) was added. The mixture was warmed to room temperature and stirred overnight. The mixture was diluted with EtOAc and washed with water. The organic layer was dried over Na2SO4, filtered and concentrated. The residue was purified by silica gel chromatography (0-15% EtOAc/hexanes) to yield the title compound as a clear oil (1491 mg). The mixture was warmed to room temperature washed with water The organic layer was dried over Na2SO4 filtered concentrated The residue was purified by silica gel chromatography (0-15% EtOAc/hexanes)

実験手順: 0.5 g of N-methylmorpholine was added to a suspension containing 1.4 g of N1 -[2-(4-cyanophenoxy)-1-methylethyl]-L-valinamide suspended in 40 ml of methylene chloride, at -15° C. After 0.9 g of phenyl chlorodithioformate was added to the mixture at -15° C., the reaction mixture was allowed to sit and warm naturally to room temperature while being stirred, and subsequently the whole mixture was stirred for 15 hours at room temperature. Water was subsequently added to the reaction mixture. After the methylene chloride layer was washed with water, the organic layer was dried over anhydrous magnesium sulfate and the methylene chloride was removed under reduced pressure. The residue was purified by column chromatography on silica gel, thus yielding 1.4 g of the desired product in the form of a yellow glutinous substance (yield: 66%). subsequently the whole mixture was stirred for 15 hours at room temperature After the methylene chloride layer was washed with water the organic layer was dried over anhydrous magnesium sulfate the methylene chloride was removed under reduced pressure The residue was purified by column chromatography on silica gel
