Participants

Reaction Conditions

Reaction Steps

A solution of 2-phenyl thiazole (200 mg, 1.24 mmol) in conc. sulphuric acid (0.5 ml) was cooled to 0° C. The nitrating mixture (made up of 0.5 ml of conc. nitric acid and 0.5 ml of conc. sulfuric acid) was added dropwise and stirred at 0° C. for 1 hr. The reaction was quenched with ice water and basified with sodium hydroxide solution. The resultant precipitate was filtered and washed with water. Purification by column chromatography over silica gel using EtOAc/pet ether gave 2-(4-nitrophenyl) thiazole (150 mg, 58.6%) as solid.
