Procedure

Compound (153) (0.030 g), phenylboronic acid (0.014 g), palladium acetate (0.001 g), tricyclohexylphosphine (0.004 g), and potassium phosphate (0.050 g) were dissolved in toluene (0.5 mL) and water (0.025 mL), followed by stirring using microwaves at 130° C. for 10 min. The reaction solution was distributed between chloroform and water, and the organic layer was washed with saturated saline and then dried over anhydrous sodium sulfate. The solvent was distilled away, and the residue was purified by neutral silica gel column chromatography (chloroform/methanol) to obtain compound (172) (0.002 g, 6%) as a white solid.
