Answer
![1-methyl-2-[(E)-2-(3-methyl-2-thienyl)vinyl]hexahydropyrimidine-1,3-diium citrate](https://static.chemtradehub.com/structs/695/69525-81-1-2f49.webp "1-methyl-2-[(E)-2-(3-methyl-2-thienyl)vinyl]hexahydropyrimidine-1,3-diium citrate")
1-methyl-2-[(E)-2-(3-methyl-2-thienyl)vinyl]hexahydropyrimidine-1,3-diium citrate (CAS: 69525-81-1) is synthesized through a multi-step process involving the alkylation of a thienyl acetylene with a hexahydropyrimidine derivative. The reaction is catalyzed by a palladium complex, and the product is then converted to the citrate salt form. The overall yield is around 70-80%, with good selectivity towards the desired product.
