Reaction Steps

To a solution of (4S,5R)-2-(4-chloro-2-ethoxy-5-methylsulfamoyl-phenyl)-4,5-bis-(4-chloro-phenyl)-4,5-dihydro-imidazole-1-carboxylic acid benzotriazol-1-yl ester (9 mg, 0.0124 mmol) in 0.5 mL of dimethylformamide was added a solution of 1-morpholin-4-yl-2-piperazin-1-yl-ethanone (5.3 mg, 0.026 mmol) and diisopropylethylamine (4.53 uL). The resulting mixture was heated to 40° C. for 1 h. The solution was concentrated in vacuo then extracted from 1 mL of water with 1 mL of methylene chloride. The organic extract was applied to a 4 gram silica gel cartridge. The product was eluted using a gradient of methanol in methylene chloride 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-N-methyl-benzenesulfonamide (9.69 mg, 97%). LC-MS: 777.3 [(M+H)+].
