Versuchsvorschrift

In a solution of the compound 23-a (100 mg) and pyridine (59 mL) in dichloromethane (3 mL), the compound 36 (74 mg) was added. The reaction mixture was stirred at room temperature for 30 minutes. To the reaction mixture, an aqueous 1N sodium hydroxide solution (15 mL) was added. The aqueous layer was extracted twice with dichloromethane (30 mL). The combined organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and then concentrated. The residue was purified by silica gel chromatography (ethyl acetate:methanol:triethylamine=10:1:0→10:1:0.5) to obtain the title compound (119 mg) having the following physical properties.
