Diisopropylethylamine → 5Chloro-1H-pyrrolo[2,3-c]pyridine-2-carboxylic acid [1-(S)-(4-fluorobenzyl)-2-oxo-2-(4-trifluoromethylpiperidin-1-yl)ethyl]amide

Participants

Reaction Steps

To 4-trifluoromethyl piperidine (17 mg, 0.11 mmol) was added a solution of 2-(S)-[(5-chloro-1H-pyrrolo[2,3-c]pyridine-2-carbonyl)amino]-3-(4-fluorophenyl)propionic acid (EXAMPLE 228, 40 mg, 0.11 mmol) in DMF (400 μL) followed by a solution of HATU (50 mg, 0.13 mmol) in DMF (400 μL) and finally a solution of DIPEA (23 μL, 0.13 mmol) in DMF (200 μL). The resulting mixture was stirred at rt for 96 h then solvent was removed in vacuo. The crude material was purified by crystallisation from THF/petroleum ether to give the title compound as a yellow powder. (ES+)=497.23 [M+H]+; RT=3.50 min.
