Reaction Steps

A mixture of [2-(4-methoxy-phenyl)-ethyl]-[2-methoxy-6-(1-trityl-1H-benzoimidazol-5-yl)-pyrimidin-4-yl]-amine [300 mg, 0.485 mmol, Intermediate (28)], DCM (5 mL), trifluoroacetic acid (2 mL) and water (5%) is stirred at ambient temperature. The reaction mixture is concentrated by rotary evaporator to remove the solvent. The residue is taken up in saturated sodium bicarbonate solution and this solution is extracted with ethyl acetate. The extract is dried over magnesium sulfate, filtered and concentrated to provide a solid, which is subjected to flash column chromatography on silica gel eluting with 5% MeOH in DCM to afford [6-(1H-benzoimidazol-5-yl)-2-methoxy-pyrimidin-4-yl]-[2-(4-methoxy-phenyl)-ethyl]-amine [90 mg, 49%, Example 14(a)]. LCMS: RT=4.73 minutes, MS: 376 (M+H). IC50=2.7 nM
