実験手順
1.30 g of tert-butyl 2-(acetylamino)-2-[3-chloro-5-(trifluoromethyl)-2-pyridinyl]ethylcarbamate (0.034 mol) are diluted in a mixture of dichloromethane (2.5 mL) and trifluoroacetic acid (2.5 mL). After stirring overnight at room temperature, the reaction mixture is concentrated to dryness to yield to 1.34 g of desired product N-{2-amino-1-[3-chloro-5-(trifluoromethyl)-2-pyridinyl]ethyl}acetamide trifluoroacetate (99%).
