(Z)-Ethyl 3-(dimethylamino)-2-(2-fluoro-5-iodobenzoyl)acrylate (0.428 g, 1.09 mmol, Intermediate 24) and 2-methoxyethanamine (0.082 g, 1.09 mmol, Acros) were combined in DMF (3.0 mL). Potassium carbonate (0.151 g, 1.09 mmol, Fisher) was added and the reaction was heated in the microwave at 90° C. for 30 min After 30 minutes, LC/MS indicated that the reaction was complete. The reaction mixture was cooled to room temperature and slowly poured into water. The resulting precipitate was filtered, washed with water and dried overnight to yield a white solid (0.277 g).
