3-Ethoxy-3-(3-methoxy-2-methyl-phenylimino)-propionic acid ethyl ester (1.56 g, 5.57 mmol) was dissolved in diphenyl ether then placed in a 300° C. sand bath. The internal temperature was kept between 240-250° C. for 15 minutes then the reaction was cooled to room temperature. The crude material was directly loaded onto a silica gel column (0→60% EtOAc/hexane) to afford 2-ethoxy-7-methoxy-8-methyl-quinolin-4-ol (882 mg, 68%). LCMS found 234.1 [M+H]+.
