実験手順

0.41 g 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, were dissolved in DMF (30 ml) and treated with NaH (0.061 g of a 65% NaH suspension in oil) under ice cooling. The mixture was stirred for 1 h at RT, treated dropwise with 0.11 g of methyl chloroacetate and was stirred at RT for 20 h until the reaction was completed according to TLC analysis (CH2Cl2/EtOAc: 4/1). The mixture was partitioned between brine 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: 7/1). Combination of the purified fractions and evacuation in vacuo afforded {3-[4-methoxy-5-(2-methoxy-phenoxy)-6-(5-methyl-pyridine-2-sulfonylamino)-pyrimidin-2-yl]-phenoxy}-acetic acid methyl ester as a light yellow crystalline solid. ISP mass spectrum, m/e 567.2 (M+1 calculated for C27H26N4O8S: 567).
