RARECHEM AN KA 1188 - Reference Information
| use | 3-butene-1-amine can be used as an intermediate in pharmaceutical synthesis. |
| Preparation | Hydrazine hydrate (20.0g,0.40mol) is added to N-(3-butene-1-yl) phthalimide (40.2g,0.20mol) in ethanol (200mL) solution. The reaction solution is heated until reflux reaction lasts for about 1.5 hours, cooled, 40mL concentrated hydrochloric acid is added dropwise, stirred for 10min, and then filtered. The pH value of the filtrate was adjusted to 7-8 with 5M potassium hydroxide aqueous solution, filtered, the filtrate was extracted with methyl tert-butyl ether (100mL * 4), organic phase was combined, anhydrous potassium carbonate was dried, filtered, and the solvent was evaporated under reduced pressure to obtain 11.5g of white solid, namely 3-butene-1-amine. |
