実験手順

14.6 g of 4-tert-butyl-N-[5-(2-chloro-5-methoxy-phenoxy)-6-methyl-2-(morpholin-4-yl)-pyrimidin-4-yl]-benzenesulphonamide and 15.9 g of selenium dioxide in 500 ml of dioxan were stirred in an autoclave at 170° C. for 6 hours. The reaction mixture was filtered and the filtrate was concentrated. The residue was partitioned between chloroform and water. The organic phase was dried, the solvent was evaporated and the residue was recrystallized from dichloromethane-ethanol. There were obtained 10.3 g of 4-tert-butyl-N-[5-(2-chloro-5-methoxy-phenoxy)-6-formyl-2-(morpholin-4-yl)-pyrimidin-4-yl]-benzenesulphonamide, m.p. 235°-236° C., MS: M=561.
