실험 절차

(3-amino-6-chloro-pyridin-2-yl)-methanol (998 mg, 4.0 mmol) is taken up in DCM and combined with MnO2 (697 mg, 8.0 mmol). After 24 h another 2 eq. MnO2 are added and the mixture is stirred for further 24 h at RT. Then the reaction mixture is filtered through Celite®, the solvent is removed and 3-amino-6-chloro-pyridine-2-carbaldehyde (HPLC-MS: tRet.=1.88 min, MS(M+H)+=157; method AFEC) is obtained.
