実験手順
3-Chlorobenzenecarboperoxoic acid (0.046 g) was added to 3-(1,3-benzoxazol-2-yl)-5-[1-(1-methyl-4-piperidyl)pyrazol-4-yl]pyridin-2-amine (0.100 g) in DCM (10 ml). The resulting solution was stirred for 5 minutes. The resultant precipitate was collected by filtration, washed with DCM (2 ml) and dried under vacuum. The residue was purified by SCX ion exchange chromatography (elution with 7M methanolic ammonia) and there was thus obtained 3-(1,3-benzoxazol-2-yl)-5-[1-(1-methyl-1-oxido-piperidin-1-ium-4-yl)pyrazol-4-yl]pyridin-2-amine (0.026 g); Mass Spectrum: M+H+ 391.29; RT 1.18 min; NMR Spectrum: (DMSOd6) 8.49 (d, 1H), 8.41 (d, 1H), 8.32 (s, 1H), 7.88 (s, 1H), 7.78 (dd, 1H), 7.73 (dd, 1H), 7.57 (br s, 2H), 7.38 (m, 2H), 4.26 (tt, 1H), 3.46 (m, 2H), 3.11 (s, 3H), 3.06 (m, 2H), 2.68 (m, 2H), 1.90 (br m, 2H).
