Reaction Steps
(E)-3-(4-Chloro-2-methanesulfonylamino-5-methoxyphenyl)-acrylic acid (100 mg; 0.32 mmol), (2R,5S)-1-(4-fluorobenzyl)-2,5-dimethylpiperazine (Mavunkel, Babu J. et al., WO 00171535) (73 mg; 0.32 mmol) and EDCl.HCl (75 mg, 0.39 mmol), HOBt (5 mg; 0.03 mmol) were dissolved in DMF (2 ml) and stirred over night. The reaction mixture was evaporated, taken up in 2N Na2CO3 and extracted with EtOAc three times. The combined organic phases were evaporated and purified via chromatography (SiO2 acetone/hexanes 3/7) to yield the title compound as yellow foam (135 mg; 81%)
