N4-((1R,4R)-4-(tert-butyldiphenylsilyloxy)-7-fluoro-1,2,3,4-tetrahydronaphthalen-1-yl)-2-(6-fluoro-1H-benzo[d]imidazol-1-yl)pyrimidine-4,5-diamine (490 mg, 0.751 mmol, 1 equiv) was dissolved in anhydrous THF (15 mL) and CDI (737 mg, 4.54 mmol, 7 equiv) was added. The reaction was stirred at RT under argon overnight. The solvent was removed by evaporation. The residue was dissolved in EtOAc (30 mL) and washed with saturated NaHCO3, water and brine, dried (Na2SO4). The organic layer was evaporated to dryness. The residue was applied to ISCO (12 g column, MeOH—CH2Cl2 0-2%) to give a white solid product (420 mg, 82%). MS (ESI): 673.3
