실험 절차

A solution of 60.1 mg (0.23 mmol) of the compound from example 1g in 1 ml of absolute DMF was mixed with 11 mg (0.23 mmol) of sodium hydride (50%) and stirred at RT for 1 h. Then 70.3 mg (0.23 mmol) of the compound from example 10a were added, and the mixture was stirred at RT for 1 h. The reaction solution was mixed with 1 ml of water and extracted several times with EA. The combined EA extracts were dried over Na2SO4, filtered and concentrated. Purification of the resulting residue by chromatography on silica gel with CH2Cl2/methanol (9:1) as mobile phase afforded 71.4 mg of the title compound.
