Reference example 14 3-(3,4-Dimethylphenylthio)-2-(2-methoxycarbonylethyl)propionic acid A mixture of 3,4-dimethylbenzenethiol (0.59 ml), 2-methyleneglutaronitrile (0.48 ml), ethanol (10 ml), and triton B (40% ethanol solution, 5 drops) was refluxed for 5 hours. After the reaction mixture was concentrated in vacuo, the resulting residue was dissolved in chloroform, washed with water, and dried over MgSO4. The solvent was evaporated at reduced pressure, and the residue was purified by flash column chromatography on silica eluding with benzene/ethyl acetate (7:1) to give 1.18 g of 2-(3,4-dimethylphenylthiomethyl)glutaronitrile as oil. IR (neat): nuCN2230 cmmin1 NMR (CDCl3)
Statistics shows that 2-Methylenepentanedinitrile is playing an increasingly important role. we look forward to future research findings about 1572-52-7.
