Reaction Steps

To a solution of 2-[1-(4-(N-naphth-1-yl-carbamoyl)-piperazin-2-yl)ethylamino]-4-[benzimidazol-1-yl]pyrimidine (EXAMPLE 36, Step C; 26 mg) in 0.5 mL of acetone was added potassium carbonate (11 mg) and ethyl bromoacetate (13.2 mg). The solution was stirred for 48 hours at room temperature, then diluted with 0.5 mL of water and extracted with 3×0.5 mL of CH2Cl2. The combined organics were washed with 1 mL of brine, dried with Na2SO4, and concentrated. The residue was purified by preparative HPLC (60:40 95% H2O-5% TFA:95% CH3CN-5% TFA) followed by preparative thin-layer chromatography, eluting with 95:5 25 CHCl3-isopropanol to provide 8.7 mg of the title compound. Mass spectrum (ESI) 579.3 (M+1).
