75336-86-6, (R)-2-Methylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
75336-86-6, (R)-2-methylpiperazine (1.25g, 12.5mmol), and K2CO3 (4.0g) were combined with chloroform (30 mL) in a 50mL flask fitted with a magnetic stirrer. A chloroform (25 mL) solution of 1-chloromethyl-4-vinylbenzene (4.00 g, 26.2 mmol) was added dropwise slowly within 30min at 40-50 °C under stirring. The reaction mixture was heated to reflux for 4h till the starting material disappeared by TLC detection (n-hexane:ethyl acetate=5:1, V/V). The resultant mixture was filtered to remove the solid. The solvent was removed from the filtrate under reduced pressure to yield a viscous oil that was then diluted with ethanol (60mL). Adding HCl/ethanol to the above solution till pH 1-2 yielded a white solid. The resultant precipitate was collected by suction filtration, washed with cold ethanol, and then mixed with water (10mL). The pasty was adjusted to pH 10-11 with ammonium hydroxide and then extracted with methylene dichloride twice (80 mL). The organic phase was washed with saturated brine and dried with magnesium sulfate. Removing solvent afforded 3.3 g (R)-MbVBP as white crystalline powders in 79.5percent yield based on (R)-2-methylpiperazine.
The synthetic route of 75336-86-6 has been constantly updated, and we look forward to future research findings.
