Reaction Steps

5-{(4S,5R)-4,5-Bis-(4-chloro-phenyl)-1-[4-(2-morpholin-4-yl-2-oxo-ethyl)-piperazine-1-carbonyl]-4,5-dihydro-1H-imidazol-2-yl}-N-tert-butyl-2-chloro-4-ethoxy-benzenesulfonamide (˜10 mg) was dissolved in 2 mL of trifluoroacetic acid and heated to 80° C. for 30 min. The reaction mixture was diluted with 2 mL of methylene chloride and 1.5 mL of 10% potassium carbonate solution then agitated. The organic layer was separated and concentrated in vacuo to give 5-{(4S,5R)-4,5-bis-(4-chloro-phenyl)-1-[4-(2-morpholin-4-yl-2-oxo-ethyl)-piperazine-1-carbonyl]-4,5-dihydro-1H-imidazol-2-yl}-2-chloro-4-ethoxy-benzenesulfonamide as trifluoroacetate salt. LC-MS: 763.3 [(M+H)+].
