301673-16-5, tert-Butyl 3-(hydroxymethyl)piperazine-1-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
4-teri-Butyloxycarbonyl-2-hydroxymethylpiperazine (4.5 g, 21 mmol) was dissolved in 50 mL of THF and to the stirred solution was added an equal volume of saturated aqueous NaHC03 solution. To the rapidly stirred biphasic mixture was added benzyl chloroformate (3.9 g, 23 mmol) dropwise over a period of 20 min. The mixture was stirred at room temp for 1.5 h, diluted with water and EtOAc, stirred for 10 min, then the aqueous phase was removed. The organic phase was washed with aqueous NaHC03, brine, then dried (MgS04), filtered, and stripped in vacuo to give a dense gum. The crude product was chromatographed on a 120 g Si02 column eluting with 0- 100percentEtOAc-hexanes. The broad peak eluting between 45-80percent EtOAc was collected to give a colorless gum. LCMS (4 min gradient, 215 nm): 2.03 min, m/z = 351.4., 301673-16-5
301673-16-5 tert-Butyl 3-(hydroxymethyl)piperazine-1-carboxylate 22386508, apiperazines compound, is more and more widely used in various fields.
