Reaction Steps
TEA (1.8 mL, 13.20 mmol) was added to a solution of 1,1-bis-methylsulfanyl-2-nitro-ethene (I-1b: 1.45 g, 8.802 mmol) and 2-amino-ethanethiol (1 g, 8.802 mmol) in ethanol (20 mL). The resulting mixture was heated to reflux for 3 hours. The reaction mixture was monitored by TLC (70% ethylacetate in hexane). The reaction mixture was concentrated to afford the crude product. Purification by column chromatography on silica gel (70% ethylacetate in hexane) afforded 0.6 g of the product (31% yield).
