실험 절차

To a mixture of ((3S,5S,6S)-1,5-bis(methoxycarbonyl)-6-[(4-phenylpiperazin-1-yl)carbonyl]piperidin-3-yloxy)acetic acid (57 mg, 0.00012 mol), pyrrolidine (0.0308 mL, 0.000369 mol), and benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (163 mg, 0.000369 mol) in N,N-dimethylformamide (0.50 mL, 0.0064 mol) was added N,N-diisopropylethylamine (0.0857 mL, 0.000492 mol). The mixture was stirred at rt for 2 h, then diluted with ethyl acetate, washed with water, brine and dired. After concentrated to dry, the residue was used directly in next step.
