N-benzyl-7-chloroquinolin-4-amine C화학적 특성, 용도, 생산
Synthesis
N-benzyl-7-chloroquinolin-4-amine is obtained by reacting 4,7-dichloroquinoline and aqueous sodium carbonate in microwave radiation.To a solution of 4,7-dichloroquinoline (100 mg, 0.50 mmol) in ethanol (3.00 ml) benzylamine (268 mg, 2.50 mmol) was added and the mixture was reacted at 165 °C for 3 hours under microwave radiation. The resultant mixture was concentrated in vacuo, aqueous sodium carbonate (10ml) was added and this was then extracted with dichloromethane (3×10 ml). The organic extracts collected was dried using magnesium sulphate and concentrated in vacuo to give the title compound as colourless crystals (34 mg, 25%): mp: 175 – 176°C (Lit.: 175 – 178 °C)110;
