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 4341-76-8 as follows. Product Details of 4341-76-8
General procedure: In a two neck rbf was stirred a mixture of Pd(OAc)2 (275 mg,1.22 mmol) and TDMPP (540 mg, 1.22 mmol) in benzene (30 ml)for 15 min at rt under nitrogen. To this mixture was added ethyl-2-butynoate 7 (2.84 ml, 24.48 mmol) and the resulting mixturewas further stirred for 10 min at rt. Next, ethynylbenzene 4a(2.50 g, 24.48 mmol) was added to this solution and the mixturewas stirred for 5-10 min until reaction was completed. Theworkup of reaction was performed by evaporating the solvent invacuum followed by column chromatography (Hexane:EtOAc = 100:1) to give the desired compound 8a (2.62 g);
According to the analysis of related databases, 4341-76-8, the application of this compound in the production field has become more and more popular.
