208167-83-3, tert-Butyl 4-(2-chloroethyl)piperazine-1-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
[0384] To a solution of l-Boc-4-(2-chloroethyl)piperazine (6.85 g, 27.62 mmol) in methanol (50 ml) was added thiourea (4.12 g, 55.24 mmol). The mixture was heated to reflux for 2 hours. A solution of sodium hydroxide (1.66 g, 41.43 mmol) in water (10 ml) was added, and the mixture was continued to reflux for another hour. Then most solvent was evaporated under reduced pressure. The residue was mixed with ethyl acetate (50 ml) and brine (30 ml) and separated. The ethyl acetate was dried over magnesium sulfate and evaporated under reduced pressure. The residue was dissolved in methanol (20 ml). 4 M hydrochloric acid in dioxane (10 ml) was added. The mixture was stirred at room temperature overnight and most of solvent was evaporated under reduced pressure. The residue was used for the addition reaction without further purification.
208167-83-3, The synthetic route of 208167-83-3 has been constantly updated, and we look forward to future research findings.
