Conditions

Temperature: 25 °C

Procedure

Compound 62 (93 mg) and zinc (147 mg) were suspended in acetic acid (2 mL) and the suspension was stirred at room temperature (20 to 30° C.) for 3 hours. Subsequently, the reaction mixture was filtered and the filtrate was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (ethyl acetate:hexane=5:1 to 3:1) to give 25.4 mg (29% yield) of the desired product as a pale yellow amorphous.
