Trifluoroacetic acid → 4-(Prop-2-enyl)-2-[(4-chlorophenoxy)methyl]-1-[3-(piperidin-4-yl)propyl]benzimidazole trifluoroacetate

Participants

Reaction Steps

In a 100 ml single neck round bottom flask, under a nitrogen atmosphere, 4-(prop-2-enyl)-2-[(4-chlorophenoxy)methyl]-1-[3-[1-(t-butoxycarbonyl)piperidin-4-yl]propyl]benzimidazole (300 mg, 0.572 mmol) was added to anhydrous methylene chloride (20 ml). To this was added trifluoroacetic acid (0.44 ml, 652 mg, 5.72 mmol). The resulting mixture is stirred overnight at room temperature. The progress of the reaction was monitored by thin layer chromatography. The solvents were removed in vacuo.
