Reaction Steps
To a solution of 2.93 g of 4-[4-(5-isopropyl-pyridine-2-sulfonylamino)-6-methoxy-5-(2-methoxy-phenoxy)-pyrimidin-2-yl]-pyridine-2-carboximidic acid methyl ester sodium salt in DMF (60 ml) was added under ice cooling NaH (0.8 g of a 60% NaH suspension in oil). The mixture was stirred for 1,5 h at 0° C. The mixture was poured into water, the pH adjusted to pH=6 and the product extracted into EtOAc. The organic layer was washed with water, dried over Na2SO4 and the solvent removed in vacuo. The residue was purified on a silica gel chromatography column (eluted with Me2Cl2/EtOAc: 5/1). Combination of the purified fractions and evacuation in vacuo afforded 5-isopropyl-pyridine-2-sulfonic acid [2-(2-cyano-pyridin-4-yl)-6-methoxy-5-(2-methoxy-phenoxy)-pyrimidin-4-yl]-amide as a light yellow crystalline solid. ISN mass spectrum, m/e 531.1 (M−1 calculated for C26H24N6O5S: 531).
