Procedure

5-Bromo-1-[2-fluoro-6-(trifluoromethyl)benzyl]-6-methyl-3-[2(R)-tert-butoxycarbonylamino-2-phenylethyl]-pyrimidine-2,4(1H,3H)-dione 1e was dissolved in 20 mL/20 mL CH2Cl2/TFA. The resulting yellow solution was stirred at room temperature for 2 hours. The volatiles were evaporated and the residue was partitioned between EtOAc/sat. NaHCO3. The organic phase was dried over Na2SO4. Evaporation gave 2a as a yellow oil.
