Procedure

The compound (5.06 g, 5.47 mmol) synthesized in Example 4 (4a) was dissolved in methanol (75 mL) and tetrahydrofuran (15 mL) and palladium chloride (II) (190 mg, 1.09 mmol) was added thereto, followed by stirring of the mixture at room temperature for 14 hours. After the reaction mixture was subjected to celite filtration, the solvent was distilled off under reduced pressure. The residue was purified using silica gel flash column chromatography (hexane:ethyl acetate, 4:1-3:1-2:1, V/V) to obtain the desired title compound (3.07 g, yield 63%) as pale yellow amorphous matter.
