実験手順

The compound obtained in Example 23-2 (350 mg) was dissolved in DMF (7 ml). After the addition of WSCI hydrochloride (265.0 g), DMAP (169 mg), and the compound obtained in Example 41-1 (276.0 mg), the mixture was stirred for 24 hours at room temperature. After the reaction, the solvent was removed by distillation. The residue was dissolved in chloroform, washed with 1 mol/l aqueous solution of hydrochloric acid and saturated aqueous solution of sodium hydrogencarbonate, and dried over sodium hydrogensulfate. The solvent was removed by distillation and the residue was purified by silica gel column chromatography (20 g, chloroform/methanol=10/1). 130 mg of the obtained product was dissolved in methanol (2.6 ml) and 4 mol/l hydrochloric acid/dioxane solution (2.6 ml) was added. The mixture was stirred for 70 minutes at room temperature. After the reaction, the solvent was removed by distillation and the residue was dried under vacuum to obtain hydrochloride of the title compound (147 mg) as a white solid.
