At the same time, in my other blogs, there are other synthetic methods of this type of compound, 15965-54-5, and friends who are interested can also refer to it.

15965-54-5, 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 15965-54-5 as follows.

General procedure: A mixture of 10 (5 mM), 11 (5 mM) in DMF (20 mL) containing K2CO3 (2 mM) and TBAB (2 mM) was stirred at RT for a period of 3-5 h. The reaction was monitored by TLC analysis. After the completion of reaction, the mixture was poured into ice-cold water (30 mL). The separated solid was filtered, washed with water (2 9 10 mL) and dried. The crude product was recrystallized from a suitable solvent to yield pure 9.
