実験手順
A suspension of (S)-4-(5-(4-(4-fluorophenyl)-2-oxooxazolidin-3-yl)pyrazolo[1,5-a]pyrimidin-3-yl)-N′-(1-iminoethyl)benzohydrazide (0.049 g, 0.104 mmol) in 1:1 DCM-acetonitrile (10 mL) was treated with carbon tetrachloride (0.040 mL, 0.414 mmol), triethylamine (0.1442 mL, 1.035 mmol) and triphenylphosphine (0.1086 g, 0.414 mmol) at ambient temperature. The mixture was heated at 50° C. for 2 hours. After cooing to ambient temperature, the mixture was treated with EtOAc, washed with water, dried (phase separator silicone treated filter paper), concentrated and purified on silica gel (2-5% MeOH in DCM) to provide (S)-4-(4-fluorophenyl)-3-(3-(4-(5-methyl-4H-1,2,4-triazol-3-yl)phenyl)pyrazolo[1,5-a]pyrimidin-5-yl)oxazolidin-2-one (0.003 g, 6% yield) as a yellow oil. LCMS (APCI+) m/z 456 [M+H]+.
