実験手順

The compound (2.00 g) obtained in (3) was dissolved in dichloromethane (10 mL), and Boc-Leu-OH (2.21 g), EDC.HCl (2.13 g), and DMAP (0.99 g) were added while stirring. After the stirring was continued for 1 day, the solvent was distilled off under reduced pressure. The resulting residue was purified by flash chromatography (ethyl acetate/chloroform=0%→25%) using silica gel column (product name: Hi-Flash Column 3 L, manufactured by Yamazen Corporation) to afford the title compound (3.20 g).
