L-Tartaric acid → HCID 66860548, compound

Participants

Reaction Steps

11.1 ml of a 0.30 M solution of 1-[2-(2,4-Dimethylphenylsulfanyl)-phenyl]piperazine in acetone was treated with 0.5 gram L-(+)-tartaric acid dissolved in 5 ml acetone. The mixture was stirred at room temperature for 30 minutes during which precipitation took place. Filtration and washing first with 5 ml acetone and then 3 ml diethyl ether achieved the product as a white solid that was dried in vacuum (50° C.) over night. 1-[2-(2,4-Dimethylphenylsulfanyl)-phenyl]piperazine (+)-tartaric acid was isolated in 1.2 gram (81%). NMR complies with structure. Elemental analysis: 58.86% C, 6.30% N, 6.38% H (Theory for a 1:1 salt: 58.91% C, 6.25% N, 6.29% H)
