실험 절차

To a solution of N-{(3S)-1-[(1S)-2-(3-aminopiperidin-1-yl)-1-methyl-2-oxoethyl]-2-oxopyrrolidin-3-yl}-6-chloronaphthalene-2-sulfonamide (0.005 g) in DMF (0.5 ml) were added propiolic acid (0.001 g), N,N-diisopropylethylamine (0.0044 ml) and o-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.004 g). The mixture was stirred at room temperature for 18 h and then concentrated under reduced pressure. The residue was partitioned between DCM and saturated sodium bicarbonate solution and then passed through a hydrophobic frit. The separated organic fraction was concentrated under reduced pressure to give the title compound (0.0064 g) as an oil.
