実験手順
A suspension of 4-chloro-7-iodo-2-methylquinoline (EP497371, 2.00 g, 6.59 mmol) in ethanol (20 mL) was treated sucessively with pyrrolidine (1.28 g, 18.0 mmol), pyridine (0.2 mL) and potassium iodide (50 mg, 0.30 mmol), and the resulting mixture was refluxed for 24 h. After concentration in vacuo, the residue was taken up in water (50 mL) and basified to pH 12 by addition of 2 M aq. sodium hydroxide solution. The precipitate was collected by filtration, washed with water (20 mL) and ether (20 mL) and dried to afford the title compound (1.95 g, 87%). Off-white solid, m.p. 99-102° C.
