Procedure
A stirred suspension of 4-{5-(cyclobutylcarbonyl)-6-methyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidin-4-yl}benzonitrile (Example 20) (29 mg, 0.066 mmol) and potassium carbonate (16.4 mg, 0.12 mmol) in dimethylformamide (1 ml) is treated with tert.-butyl bromoacetate (14.2 mg, 0.073 mmol), and then stirred at room temperature overnight (16 h). The reaction solution is quenched with water (3 ml) and extracted with diethyl ether (2×5 ml). The combined organic phases are washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated.
