Trifluoroacetic acid (6.05 g, 53.04 mmol, 3 eq) in dichloromethane (50 ml) is added to a solution of di-tert-butyl 2-oxo-4-(3,3,3-trifluoropropyl)imidazolidine-1,3-dicarboxylate a7 (6.76 g, 17.68 mmol, 1 eq) in dichloromethane (60 ml) at room temperature overnight. The reaction mixture is condensed under reduced pressure to afford 4.22 g of 4-(3,3,3-trifluoropropyl)imidazolidin-2-one a10 as a yellow oil.
