Procedure

To a solution of compound 1g (228 mg, 0.74 mmol), compound 25c (22 mg, 0.74 mmol), and Et3N (0.3 mL, 2.22 mmol) in CH2Cl2 (7 mL) was added HATU (338 mg, 0.89 mmol). The reaction mixture was stirred at room temperature for 18 h. The resultant mixture was diluted with CH2Cl2 and washed with aqueous NaHCO3. The organic phase was dried over Na2SO4, filtered, and concentrated under reduced pressure. Purification of the residue by flash column chromatography (silica gel, 2% MeOH/EtOAc+0.5% Et3N) gave compound 25d (265 mg). LC/MS m/z (M+H+), 517.0 (M+2H+), 519.0.
