実験手順

To a solution of N-methyltetrahydro-2H-pyran-4-amine (172.5 mg, 1.5 mmol) in CH3CN (5 mL) was added K2CO3 (207 mg, 1.5 mmol) and 2-bromo-5-nitropyridine (203 mg, 1 mmol). The reaction was stirred at 80° C. for 16 hours. TLC and LC-Ms showed the reaction had completed and the reaction was poured into water, extracted with EA, washed with water and brine, dried and concentrated to give a yellow solid. MS (m/z): 238 (M+H)+
