Reaction Steps

4-Amino-cyclohexanecarboxylic acid (84 mg, 0.573 mmol) was added to a solution of A4 (200 mg, 0.478=01) and DIEA (0.125 mL, 0.717=01) in 15 mL of DMF. The mixture was stirred at r.t. LC-MS was used to determine completion of the reaction. DMF was evaporated under reduced pressure and the residue was triturated with ACN for several times to provide 4-({5-[5-Fluoro-2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrole-3-carbonyl}-amino)-cyclohexanecarboxylic acid (180 mg, 88.5%).
