Reaction Steps

To a solution of 4-phenyl-1-(2-(pyridin-4-yl) methoxybenzoyl) semicarbazide (110 mg, 0.47 mmol; Reference Compound 6-(1) and triphenylphosphine (190 mg, 0.71 mmol) in a mixed solvent of methylene chloride (3.0 mL) and tetrahydrofuran (3.0 mL) were added carbon tetrachloride (290 mg, 1.9 mmol) and triethylamine (70 mg, 0.71 mmol), and then the mixture was refluxed overnight. The reaction solution was cooled to room temperature and ethyl acetate was added thereto. The ethyl acetate solution was washed with a saturated brine solution. To the solution was added a 1M hydrochloric acid and then the aqueous layer was taken out. To the aqueous layer was added a 1 M aqueous sodium hydroxide solution. The solid which precipitated at pH 8 was filtered off and dried under a reduced pressure to give 65 mg (40%) of the titled compound as a colorless solid.
