To pyridin-3-ylmethyl-carbamic acid tert-butyl ester (3.89 g, 18.7 mmol) dissolved in EtOH (50 mL), was added 3-chloroperoxybenzoic acid (4.7 g, 27.4 mmol). After 4 hours the volatiles were removed in vacuo and the crude was redissolved in CH2Cl2 (25 mL). To this solution was added TFA (25 mL) and the reaction was stirred at 25° C. for 2 h then the volatiles were removed in vacuo. The crude was redissolved in CH2Cl2 and evaporated. This procedure was done twice more. (1-Oxy-pyridin-3-yl)-methylamine was obtained with contamination of 3-chlorobenzoic acid, but carried further without any additional purification (2.74 g).
