実験手順

4-Fluoronitrobenzene (21 g) was reacted with 1H-1,2,3-triazole (12.4 g) in the same manner as in Reference Example 9. The resultant was cooled and poured into water. The precipitated crystals were collected by filtration and purified by silica gel chromatography (eluent: dichloromethane to dichloromethane/acetone=8/1). The first eluted fraction was recrystallized from dichloromethane-diisopropyl ether to give 2-(4-nitrophenyl)-2H-1,2,3-triazole (18.8 g) as pale yellow prisms.
