Adding a certain compound to certain chemical reactions, such as: 626-01-7, name is 3-Iodoaniline, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 626-01-7, Quality Control of 3-Iodoaniline
General procedure: In a 10-ml round-bottom flask equipped with a condenser, a mixture of the aromatic amine (2 mmol), ethyl acetoacetate (1 mmol), and [Pyridinium-SO3H]HSO4 (0.0,385 g, 15 mol %) was stirred at 100 C for 10 min. Afterwards, the aromatic aldehyde (2 mmol) was added, and the resulting mixture was kept under stirring for the specified time in Table 3, the progress of the reaction was followed by TLC. After completion of the reaction, the reaction mixture was cooled to room temperature, extracted by the warm EtOAc (10 ml) to separate the catalyst. EtOAc was removed and the crude product was recrystallized from aqueous ethanol (96 %) to afford the pure product, which required no further purification. The recovered catalyst was washed with EtOAc (2 x 10 ml), dried, and reused, without considerable catalytic activity decrease.
