Reaction Steps

A mixture of 5-amino-3-(4-fluorophenyl)-4-(pyridin-4-yl)pyrazole (100 mg), 1,2-bis-(4-fluorophenyl)-2-hydroxyethan-1-one (167 mg) and concentrated hydrochloric acid (1 ml) in ethanol was refluxed for 5 hours. The reaction mixture was concentrated in vacuo and the obtained crystalline was washed with hot ethanol to give 2,3,6-tris-(4-fluorophenyl)-7-(pyridin-4-yl)-1H-imidazo[1,2-b]pyrazole hydrochloride (50 mg).
