実験手順

220 mg of 4-[4-methoxy-5-(2-methoxy-phenoxy)-6-(5-methyl-pyridine-2-sulfonylamino)-pyrimidin-2-yl]-pyridine-2-carboxylic acid, product of example 21, suspended in acetontrile (10 ml) was treated at RT subsequently with 27 mg of methanol, 100 mg of 4-(dimethylamino)pyridine (DMAP) and 186 mg of benzotriazol-1-yloxytris-(dimethylamino)-phosphonium hexafluorophosphate (BOP). The mixture was stirred for 12 h at RT, then partitioned between cold diluted HCl and EtOAc. The layers were separated, the organic layer dried over Na2SO4 and the solvent removed in vacuo. The residue was purified on a silica gel chromatography column (eluted with Me2Cl2/MeOHc: 95/5). Combination of the purified fractions and evacuation in vacuo afforded 4-[4-methoxy-5-(2-methoxy-phenoxy)-6-(5-methyl-pyridine-2-sulfonylamino)-pyrimidin-2-yl]-pyridine-2-carboxylic acid methyl ester as a white solid. ISN mass spectrum, m/e 536.2 (M−1 calculated for C25H23N5O7S: 536).
