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
5464-12-0, 10.0 g Preparation B2 (37.2 mmol), 8.7 g 2-(4-methylpiperazin-1-yl)ethanol (60.3 mmol) and 15.8 g PPh3 (60.3 mmol) were dissolved in 100 mL dry toluene and then 27 mL diethyl azodicarboxylate (60.3 mmol, 40 percent solution in toluene) was added dropwise. The mixture was stirred at 50 °C under argon until no further conversion was observed. The volatiles were evaporated under reduced pressure and 100 mL Et20 was added. Theprecipitated white crystals were filtered off and washed with Et20. The filtrate was concentrated under reduced pressure and purified via flash chromatography using CHC13 and MeOH as eluents. The resulting light brown oil was crystallized from hexane to give Preparation B4 as an off-white solid. 1H NMR (500 MHz, DMSO-d6) oe: 7.56 (d, 1H), 6.99 (d, 1H), 4.15 (t, 2H), 2.72 (t, 2H), 2.51 (s, 3H), 2.50 (br s, 4H), 2.29 (br s, 4H), 2.13(s, 3H), 1.29 (s, 12H)
As the paragraph descriping shows that 5464-12-0 is playing an increasingly important role.
