Trifluoroacetic acid → HCID 86609413, compound

Participants

Reaction Steps

To a solution of (E)-4-(acetylsulfanyl)-3-{[1-(t-butoxycarbonyl)-1H-imidazol-2-yl]methylidene}-1-(triphenylmethyl)piperidine (0.72 g) in dichloromethane (20 ml) was added trifluoroacetic acid (0.29 ml) under ice-cooling, and the resulting mixture was stirred at the same temperature for 15 minutes. The reaction mixture was evaporated in vacuo, and the residue was purified by chromatography on a silica gel column using a mixed solvent of methanol and dichloromethane (1:20 to 1:10) as the eluent to afford the title compound (0.58 g, yield: quantitative) as a colourless amorphous solid.
