الإجراء التجريبي

10 g (35.4 mmol) of N-(3-chloro-phenyl)-4-(4-pyridyl)-2-pyrimidineamine and 11.1 g (35.4 mmol) of m-chloroperbenzoic acid are stirred for 5 h at RT in 500 ml of methylene chloride. Concentration and crystallisation (acetic acid) of the residue give N-(3-chloro-phenyl)-4-(N-oxido4-pyridyl)-2-pyrimidineamine; m.p. 274°-275°, Rf =0.6 (methylene chloride:methanol=9:1).
