反应详情

52 mg (0.17 mmol) of the compound from Example 1A and 89 mg (0.18 mmol) of the compound from Example 28A, together with 42 mg (0.50 mmol) of sodium bicarbonate, are suspended in 1.8 ml of dry DMF. The reaction mixture is stirred at RT for 12 h. The mixture is then filtered and the filtrate is purified directly by preparative HPLC (column: YMC GEL ODS-AQ S-5/15 μm; mobile phase gradient: acetonitrile/water 10:90→95:5). After removal of the solvent on a rotary evaporator, the product is obtained as a white solid.
