Step 1: Synthesis of N-methylpyrimidin-2-amine
To a solution of 2-chloropyrimidine (1 g, 8.7 mmol) in methanol (10 mL) was slowly added a methanolic solution of 2Methylamine (13.2 mL, 26.2 mmol) followed by potassium carbonate (2.5 g, 18 mmol). The reaction flask was sealed and the reaction was stirred at 80 °C overnight. Upon completion of the reaction, the mixture was cooled to room temperature and concentrated by rotary evaporator to remove volatile solvents. The residue was extracted by liquid-liquid partition with distilled water and dichloromethane. The organic layer was separated, dried over anhydrous sodium sulfate, filtered and concentrated to give 2-methylaminopyrimidine (290 mg, 30% yield) as a brown oil. | [References]
