General procedure for the synthesis of 2-(Boc-amino)-3-methylpyridine from 2-amino-3-methylpyridine and di-tert-butyl dicarbonate: di-tert-butyl dicarbonate (50.0 g) was dissolved in n-hexane (55 mL), heated to 58 °C with continuous stirring. Subsequently, a solution of ethyl acetate (20 mL) of 2-amino-3-methylpyridine (15.5 g) was added slowly and dropwise to this solution. The reaction mixture was heated and stirred at 58°C for 3 hours and then cooled to room temperature. The reaction mixture was diluted by addition of hexane (30 mL) and stirring was continued for 1.5 hours. The precipitated white solid precipitate was collected by filtration and dried to give 25.8 g of 2-(Boc-amino)-3-methylpyridine in 86% yield. Mass spectrometry (FAB) analysis showed m/z: 209 (M + H)+. | [References]
