1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 66751064, compound

Participants

Reaction Steps

A mixture of 2-[4-(2-tert-butylphenyl)piperazin-1-yl]-2-oxoacetic acid (Example 44, 0.40 g, 1.38 mmol), methyl 3-(4-aminophenyl)propanoate (0.30 g, 1.66 mmol), EDCI (0.26 g, 1.66 mmol) and HOBt (0.25 g, 1.66 mmol) in N,N-dimethylformamide (5 mL) was stirred at room temperature for 4 days. The reaction mixture was poured into saturated NaHCO3 solution and extracted with ethyl acetate. The extract was washed with saturated NaHCO3 solution and brine, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate 85:15 to 50:50) to give the title compound (0.56 g, 91%) as a white amorphous.
