Procedure
0.27 g of 2-[6-(4-tert.butyl-phenylsulphonylamino)-2-formyl-5-(3-methoxy-phenoxy)-pyrimidin-4-yloxy]-ethyl acetate and 0.19 g of dicyclohexyl-18-crown-6 in 15 ml of benzene were stirred with 0.078 g of potassium permanganate at 2000 for 16 hours. The reaction mixture was partitioned between toluene and water. The organic phase was dried and evaporated, and the residue was purified over silica gel with chloroform-methanol. 0.09 g of 4-(2-acetoxy-ethoxy)-6-(4-tert.butyl-phenylsulphonylamino)-5-(3-methoxy-phenoxy)-pyrimidine-2-carboxylic acid was obtained as a foam, MS: (M-H)- 558.
