Procedure

200 mg (0.32 mmol) of the crude product from example 31A, 90 mg (0.36 mmol) of 4-(chloromethyl)-2-(4-chlorophenyl)-1,3-oxazole and 82 mg (0.97 mmol) of sodium bicarbonate are added to 3.4 ml of dry DMF, and the mixture is stirred at RT for 20 h. The mixture is then purified directly by preparative HPLC (column: YMC GEL ODS-AQ S-5/15 μm; mobile phase gradient: acetonitrile/water 10:90→95:5).
