YieldReaction ConditionsOperation in experiment
With bromine; isopentyl nitrite; In chloroform; at 20℃; for 1.5h; (ii) Ethyl 5-amino-1-(4-fluorophenyl)-1 H-pyrazole-4-carboxylate (6.83 g, 27.40 mmol) was dissolved in chloroform (180 ml) and bromine (3.23 ml, 63.03 mmol) was added to give a dark red/brown solution. To this isoamyl nitrite (5.52 ml, 41.10 mmol) was added dropwise and the mixture was then stirred at room temperature for 1.5 hrs. The solvent was evaporated to give ethyl 5-bromo-1-(4-fluorophenyl)-1 H-pyrazole-4- carboxylate (15.56 g) as an orange/brown oil which solidified on standing. This was used in the subsequent step without further purification.
