4,6-Dichloro-5-(2-methoxy-phenoxy)-2-morpholin-4-yl-pyrimidine is treated with 5-isopropyl-pyridine-2-sulfonamide potassium salt to form 5-isopropyl-pyridine-2-sulfonic acid 6-chloro-5-(2-methoxy-phenoxy)-2-morpholin-4-yl-pyrimidin-4-yl-amide. This compound is then added to a solution of sodium in ethylene glycol. After heating, 5-isopropyl-pyridine-2-sulfonic acid 6-(2-hydroxy-ethoxy)-5-(2-methoxy-phenoxy)-2-morpholin-4-yl-pyrimidin-4-yl-amide is obtained and then added to a solution of pyridine-2-carbonyl azide in dioxane to form pyridin-2-yl-carbamic acid 2-[6-(5-isopropyl-pyridine-2-sulfonylamino)-5-(2-methoxy-phenoxy)-2-morpholin-4-yl-pyrimidin-4-yloxy]-ethyl ester (see EP 0713875A1).
