5464-12-0, 1-(2-Hydroxyethyl)-4-methylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
1-(2-Chloroethyl)-4-methylpiperazine (58b) was prepared by refluxing 2-(4- methylpiperazin-1-yl)ethanol (58a) (1.1 g, 7.33 mmol) with thionyl chloride (10 mL). The reaction mixture was cooled to 20 °C, and poured into ice/water. The aqueous solution was then treated with 6-bromo-4-hydroxy-2-methyl-9H-xanthen-9-one (28b) (260 mg, 0.85 mmol), tetrabutylammonium bromide (100 mg), KOH (1.12 g, 20 mmol), and CH2C12 (50mL), and the mixture was stirred for 3 days. The CH2C12 layer was separated, and the aqueous layer was further extracted with CH2C12. The combined CH2C12 extracts were dried (Na2SO4) and the solvent was removed. Chromatography on neutral alumina eluting with 0-20percent hexanes/EtOAc followed by 0-1percent CH2C12/MeOH gave crude material which was re-columned in Si02 eluting with 20percent hexanes/EtOAc to remove impurities, then with0-4percent CH2C12/MeOH to elute 6-bromo-2-methyl-4-(2-(4-methylpiperazin- 1 -yl)ethoxy)-9H- xanthen-9-one (58c): MS (APCI) m/z: 431 and 433 (M+H). This was used directly without further purification., 5464-12-0
The synthetic route of 5464-12-0 has been constantly updated, and we look forward to future research findings.
