실험 절차

49.5 mg of 5-methyl-pyridine-2-sulfonic acid [2-(3-hydroxy-phenyl)-6-methoxy-5-(2-methoxy-phenoxy)-pyrimidin-4-yl]-amide, product of example 1, dissolved in acetontrile (3 ml) was treated at RT subsequently with 25.8 mg of n-ethyldiisopropylamine, 53 mg of benzotriazol-1-yloxytris-(dimethylamino)-phosphonium hexafluorophosphate and, 0.5 h later, with 72 mg of acetic acid. The mixture was stirred for 12 h, partitioned between water and EtOAc. The organic layer was dried over Na2SO4 and the solvent removed in vacuo. The residue was purified on a silica gel chromatography column (eluted with Me2Cl2/EtOAc: 8/1). Combination of the purified fractions and evacuation in vacuo afforded acetic acid 3-[4-methoxy-5-(2-methoxy-phenoxy)-6-(5-methyl-pyridine-2-sulfonylamino)-pyrimidin-2-yl]-phenyl ester as a white solid. ISP mass spectrum, m/e 537.2 (M+1 calculated for C26H24N4O7S: 537).
