N,N′-dimethylethylenediamine (165 μL, 1.550 mmol) and anhydrous toluene (1 mL) were added under argon. The tube was sealed and the reaction mixture was stirred magnetically at 110° C. for 24 h. The resulting suspension was cooled to room temperature, 2 mL of ethyl acetate, 1 mL of ammonium hydroxide (30%) and 1 mL of water were added. The mixture was stirred at 25° C. for 10 min then the organic layer was washed with 1 mL of water and dried over MgSO4. The GC analysis showed complete conversion of starting material with formation of title product (confirmed by GC-MS).
