Conditions

Temperature: 60 °C

Procedure

Compound 454 (1.67 g, 6.00 mmol) and DMAP (36.7 mg, 0.300 mmol) were suspended in pyridine (24 mL), and cyclopropanecarbonyl chloride (1.09 mL, 12.0 mmol) was added thereto, followed by stirring at 60° C. for 90 minutes. The reaction mixture was poured into water, and the precipitated solid was collected by filtration. The resulting solid was purified through silica gel column chromatography (chloroform:methanol=99:1), followed by recrystallizing from ethanol to afford the entitled Compound 456 (1.35 g, 65%) as a white solid.
