Reaction Steps

To a stirred solution of 3-Piperazin-1-ylmethyl-pyrimido[5,4-e][1,2,4]triazine-5,7-diamine TFA salt 5 (50 mg; 0.08 mmol; prepared in EXAMPLE 4) in dry DMF (1.0 mL) was added m-bromobenzyl bromide (34 mg; 0.14 mmol) followed by potassium carbonate (55 mg; 0.40 mmol). The mixture was allowed to stir for 24 h at room temperature then taken up into CH3CN/H2O/0.1% TFA. The mixture was purified by reverse phase HPLC (Rainin C18, 0% CH3CN to 50% CH3CN gradient, CH3CN/H2O, 0.1% TFA) and the bright yellow fractions containing the product were lyophilized after removal of CH3CN in vacuo to give 15 mg of yellow colored 3-[4-(3-Bromo-benzyl)-piperazin-1-ylmethyl]-pyrimido[5,4-e][1,2,4]triazine-5,7-diamine as the trifluoroacetate salt.
