Reaction Steps

5.0 g of 4-chloro-6-((S)-2,2,2-trifluoro-1-methylethylamino)-5-(2,4,6-trifluorophenyl)-pyrimidine-2-carbonitrile (see WO 03/04993, pages 28 and 29) were initially charged in 5 ml of DMSO, 344 mg of K2CO3 were added and the mixture was cooled to 10° C. 1.4 ml of 30% strength H2O2 were then added. The mixture was stirred in an ice bath for 5 min and then at room temperature for another 30 min. The reaction mixture was introduced into 150 ml of water. During the addition, the amide precipitated out. The amide was filtered off, washed and dried under high vacuum. This gave 4.7 g of the beige title compound of m.p. 157-162° C.
