Procedure

A mixture of ethyl (4-methyl-6-nitropyridin-3-yl)acetate (1.65 g, 7.36 mmol) and palladium on carbon (10%, 1.57 g, 1.47 mmol) in Ethanol (10 mL) was evacuated and refilled with nitrogen (3×), then stirred under an atmosphere of hydrogen for 2 h. The reaction mixture was filtered through celite and concentrated in vacuoto provide title compound which was used directly in the next reaction without further purification: LC-MS (IE, m/z): 195 [M+1]+.
