Procedure
A suspension of 6-iodo-4-methoxy-quinoline-3-carboxylic acid methyl ester (example 1d) (1.7 g, 5 mmol) in ammonium hydroxide (28%, 75 mL) was heated at 150° C. for 4 days under pressure tube. After cooling, the solvent was removed by rotary evaporator. The solid was collected by filtration, washed with water and dried to obtain 6-iodo-4-methoxy-quinoline-3-carboxylic acid amide (1.4 g, 88%) as a black solid. LC-MS m/e 329 (MH+).
