The reaction of methyl 3-(arylamino)acrylates with hydrogen iodide gave 1,2-dihydroquinoline-3-carboxylic acid derivatives at room temperature. This reaction proceeds efficiently in alcoholic solvent; bulky tert-butyl alcohol is the best solvent to give the 1,2-dihydroquinoline derivatives. It is particularly interesting that hydrogen iodide is the most efficient acid to achieve this reaction in tert-butyl
