In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 689291-89-2 as follows. Safety of 5-Bromo-2-iodobenzaldehyde
Intermediate 21; N-[(l£)-(5-bromo-2-iodophenyI)methylidene]-2-methyl-2- ropanamine; To a solution of 2-1, 4-Br benzaldehyde (2.0 g, 6.4 mmol) in anhydrous THF (10 mL) was added tert-butylamine (2.0 mL, 19.3 mmol) and the reaction stirred at room temperature under a nitrogen atmosphere for 4 days. The reaction was concentrated in vacuo and partitioned between dichloromethane and water. The organic layer was dried over anhydrous sodium sulfate and concentrated in vacuo to afford the desired compound as a pale yellow solid in quantitative yield.
