실험 절차

A mixture of 3-methyl-N-(pyrrolidine-1-carbonothioyl)but-2-enamide (230 mg, 1.08 mmol, Eq: 1.00), sodium carbonate (121 mg, 1.14 mmol, Eq: 1.05) and iodomethane (769 mg, 339 μl, 5.42 mmol, Eq: 5) in tetrahydrofuran (7 ml) was stirred for 18 hours at 70° C. The crude material was applied on silicagel and purified by flash chromatography over a 20 g silicagel column using heptane/ethyl acetate 50-100% as eluent affording 3-methyl-but-2-enoic acid 1-methylsulfanyl-1-pyrrolidin-1-yl-meth-(Z)-ylideneamide (119 mg/48.5%) as a light yellow liquid. MS: m/e=227.1 (M+H+)
