Versuchsvorschrift

A suspension of 100 mg of 5-methyl-pyridine-2-sulfonic acid [2-(2-cyano-pyridin-4-yl)-6-methoxy-5-(2-methoxy-phenoxy)-pyrimidin-4-yl]-amide, product of example 19, in dioxane (10 ml) was treated at RT with 0.17 ml of N-etyldiisopropylamine then with 69 mg of hydroxylamine hydrochloride and refluxed 12 h until the reaction was complete according to TLC analysis. The mixture was poured into cold diluted HCl and the product extracted into AcOEt. The organic layer was dried over Na2SO4 and the solvent removed in vacuo. The solid residue was crystallised from CH2Cl2/Et2O to afford N-hydroxy-4-[4-methoxy-5-(2-methoxy-phenoxy)-6-(5-methyl-pyridine-2-sulfonylamino)-pyrimidin-2-yl]-pyridine-2-carboxamidine as off-white crystals. ISN mass spectrum, m/e 536.2 (M−1 calculated for C24H23N7O6S: 536).
