Procedure

4-t-Butyl-N-[6-(3-hydroxypropyloxy)-5-(2-methoxyphenoxy)-2-morpholino-4-pyrimidinyl]-benzenesulfonamide (800 mg) was dissolved in dimethylformamide (40 ml). Pyridinium dichromate (2.63 g) was added to the solution, and the resultant mixture was stirred for 14 hours at room temperature. Ethyl acetate was added to the reaction mixture, followed by successive washing with 0.5N-HCl, water, and brine. The organic layer was dried over anhydrous sodium sulfate and, evaporated. The residue was purified by silica gel column chromatography (chloroform:methanol=25:1), to thereby obtain 128 mg (yield: 16%) of the title compound as a white powder.
