Versuchsvorschrift

To a solution of 4-chloro-N-(cyclobutylmethyl)-N-(2-fluoro-4-hydroxybenzyl)-1H-pyrrole-2-carboxamide (0.040 g, 0.118 mmol) in 3 mL ethyl acetate was added Boc-iso-Valine (0.026 g, 0.118 mmol), DCC (0.037 g, 0.178 mmol) and pyridine 0.5 mL. The reaction mixture was added at r.t. for overnight. After removal of all the solvent, the residue was purified by chromatography. (0-30% methanol/DCM) (S)-4-((3-chloro-N-(cyclobutylmethyl)-1H-pyrazole-5-carboxamido)methyl)-3-fluorophenyl 2-(Boc-amino)-2-methylbutanoate was obtained (0.030 g, 0.056 mmol, 47% yield).
