To a solution of 3-[3-[[4-[(3-aminopropyl) amino] -5-bromo-2- pyrimidinyl] amino] PHENYL-2, 4-IMIDAZOLIDINEDIONE hydrogen chloride salt (6.9 g, 13.9 mmol), (-)-2-OXO-4-THIAZOLIDINECARBOXYLIC acid (2.5 g, 17 mmol, 1.2 equiv. ) and N,N-diisopropylethylamine (10 mL, 57.4 MMOL, 4.1 equiv. ) in DIMETHYLFORMAMIDE (150 mL) was added 0-(7-AZABENZOTRIAZOL-1-YL)-N, N, N’, N’ tetramethyluronium HEXAFLUOROPHOSPHATE (6.5 g, 17.1 MMOL, 1.2 equiv. ) at 0 C. The resulting solution was warmed to room temperature and stirred overnight. The reaction mixture was concentrated under reduced pressure to remove dimethylformamide. The crude residue was triturated in water to give a suspension. The suspension was filtered and the filter cake was washed with water and air-dried (ca. 8 g). The solid was purified by HPLC chromatography using acetonitrile/water to afford the title compounds, (4R)-N-[3-[[5-bromo-2-[[3- (2, 5-dioxo-1-imidazolidinyl) phenyl] amino]-4-pyrimidinyl] amino] PROPYL]-2-OXO-4- thiazolidinecarboxamide (2.8 G) and (4R)-N-[3-[[5-bromo-2-[[3-[2,5-dioxo-3-[[(4R)- 2-oxo-4-thiazolidinyl] carbonyl]-1-imidazolidinyl] phenyl] amino]-4- pyrimidinyl] amino] propyl]-2-oxo-4-thiazolidinecarboxamide (72 mg).
