反応手順

300 mg (1.05 mmol) of 3-(3-nitrophenyl)-4-[(trimethylsilyl)ethynyl]-1H-pyrazole were suspended in 60 ml of methanol and 120 mg (2.1 mmol) of potassium fluoride were added and the mixture stirred at room temperature overnight. After this time the solvent was removed under reduced pressure and the residue taken up with dichloromethane and washed with water. The organic layer was then dried over sodium sulphate and evaporated. The crude was finally purified by flash-chromatography on a silica gel column (CH2C12-CH3COCH3 9/1), giving 150 mg (67%) of the title compound.
