Reaction Steps

2-{(4-pentyl-benzyl)-[3-(4-trifluoromethyl-phenyl)-acryloyl]-amino}-(S)-3-phenyl-propionic acid (50 mg, 0.095 mmol) was dissolved in acetonitrile (1.0 ml), TBTU (37 mg, 0.115 mmol), DIPEA (37 mg, 0.29 mmol) and 1-formylpiperazine (12.23 mg, 0.105 mmol) was added and the mixture was stirred for 16 h at rt, filtered and directly purified by prep. HPLC to give 32 mg of N—[(S)-1-benzyl-2-(4-formyl-piperazin-1-yl)-2-oxo-ethyl]-N-(4-pentyl-benzyl)-3-(4-trifluoromethyl-phenyl)-acrylamide. LC-MS: tR=1.17 min; [M+H]+=620.50.
