Vorschrift

0.2 ml of Hunig base, 0.052 g of bis-(2-oxo-3-oxazolidinyl)-phosphinic acid chloride and 0.01 ml of aniline were added to a solution of 0.053 g of 6-(4-tert.butyl-phenylsulphonylamino)-4-(2-hydroxy-ethoxy)-5-(3-methoxy-phenoxy)-pyrimidine-2-carboxylic acid in 5 ml of acetonitrile. After 3 hours the reaction mixture was evaporated and partitioned between ethyl acetate and water. The organic phase was dried and evaporated, and the residue purified over silica gel with chloroform. There was obtained 0.032 g of 6-(4-tert.butyl-phenylsulphonylamino)-4-(2-hydroxy-ethoxy)-5-(3-methoxy-phenoxy)-pyrimidine-2-carboxylic acid phenylamide, m.p. 143° C., MS: (M-H)- 591.
