To the suspension of 4-chloro-6-iodo-quinoline-3-carboxylic acid ethyl ester (example 1c, 1.5 g, 4.1 mmol) in anhydrous ethanol (25 mL) was added sodium ethoxide (0.7 g, 10.3 mol). The mixture was heated to 100° C. under a pressure tube and stirred for 4 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-ethoxy-quinoline-3-carboxylic acid ethyl ester (0.58 g, 38%) as a yellow solid. LC-MS m/e 372 (MH+)
