Procedure
To a solution of Compound 47 (1 ml) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (19 mg, 0.099 mmol) and 1-hydroxybenzotriazole (catalytic amount). Dimethylamine (0.04 ml, M=2 in tetrahydrofuran) and diisopropylethylamine (0.1 ml) were added to the above solution at ice bath. The resulted solution was stirred at room temperature for 3 days. The reaction was quenched with 1 N HCl and extracted with dichloromethane. The combined organic extracts were dried over anhydrous sodium sulfate, filtrated through silica gel, and concentrated by rotary evaporation. Purification by radial preparative-layer chromatography (ethyl acetate/hexanes 50/50 to methanol/chloroform 2/98) provided 12 mg of Compound 48 as a yellow solid.
