反応手順
500 mg (1.37 mmol)of N-[3-(1,1,2,2-tetrafluoroethoxy)phenyl]-4-(4-pyridyl)-2-pyrimidine-amine are suspended in 10 ml of methylene chloride and to the suspension are added 430 mg(1.37 mmol) of m-chloroperbenzoic acid and the reaction mixture is stirred for 4 hours at RT. After extraction with water and 2N sodium hydroxide solution, the organic phase is dried and concentrated on a rotovap. Chromatography (methylene chloride:methanol=19:1 to 9:1) and subsequent crystallisation (methylene chloride:diethyl ether) give N-[3-(1,1,2,2-tetrafluoroethoxy)phenyl]-4-(N-oxido-4-pyridyl)-2-pyrimidine-amine in the form of lemon yellow crystals; FAB-MS: 381 (M+ +H), m.p. 191°-192°.
