実験手順
To the suspension of 4-chloro-6-iodo-quinoline-3-carboxylic acid ethyl ester (14 g, 0.039 mol) in anhydrous methanol (180 mL) was added sodium methoxide (4.16 g, 0.07 mol). The mixture was heated to 100° C. under a pressure tube and stirred for 10 h. After cooling to room temperature, the ice water was added. The solid was collected by filtration, washed with water and dried to obtain 6-iodo-4-methoxy-quinoline-3-carboxylic acid methyl ester (12 g, 92%) as a yellow solid. LC-MS m/e 344 (MH+)
