実験手順

In a 1 l, three-necked flask fitted with a magnetic stirrer and a reflux condenser under inert atmosphere, 4-cyano-1-methyl-1H-imidazole-5-carboxylic acid x84 (24.5 g, 0.162 mol) and CH2Cl2 (500 ml) are stirred at room temperature. To this suspension, ethanethiol (13.2 ml, 0.178 mol) and DMAP (1.98 g, 0.016 mol) are added, followed by DCC (36.77 g, 0.178 mol) in two portions. The temperature rises to 35° C. and the mixture is stirred at room temperature for 16 h. Ethanethiol (0.0324 mol) is further added and stirring is continued overnight. The mixture is filtered and the solvent is evaporated. The residue is purified by chromatography on silicagel (Hexane/AcOEt:6/4 (v/v)) to give 29.5 g of S-ethyl 4-cyano-1-methyl-1H-imidazole-5-carbothioate x85.
