Procedure
To a stirred suspension of 4-{6-methyl-2-oxo-5-(pyridin-3-ylcarbonyl)-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidin-4-yl}benzonitrile (Example 21A) (100 mg, 0.22 mmol and potassium carbonate (60 mg, 0.43 mmol) in dimethylformamide (3 ml) is added methyl 2-(chloromethyl)-1,3-oxazole-4-carboxylate (57 mg, 0.32 mmol). The reaction mixture is stirred for 72 hours at room temperature. The crude product is quenched with water (20 ml) and extracted with ethyl acetate (3×50 ml). The combined organic phases are washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated. The residue is purified by preparative HPLC (RP18 column; eluent: acetonitrile/water 30:70→90:10).
