실험 절차

0.8 g (4.47 mmol) of 5-trifluoromethyl-pyridine-2-thiol is placed at −8° C. in 16 mL of H2SO4. 16.96 mL (35.7 mmol) of a 13% sodium hypochlorite solution is poured gently such that the temperature of the reaction medium does not exceed 5° C. This mixture is then stirred for 45 min, taken up by water and then extracted using AcOEt. After drying followed by reduction to dryness of the organic phases, an oil is isolated (yield: 79%) and used as such for the next reactions.
