639068-43-2, tert-Butyl 3,5-dimethylpiperazine-1-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,639068-43-2
3,5-Dimethylpiperazine-1-carboxylic acid tert-butyl ester (1.676 g) and 2-chloropyrimidine (716 mg) were combined, melted in an oil bath at 120¡ãC, and stirred for 5 hr 30 min. Water (10 ml) was added and the mixture was stirred, extracted with ethyl acetate (30 ml), and washed with saturated brine. The extract was dried over anhydrous sodium sulfate, and the solvent was evaporated. The obtained residue was purified by column chromatography (Yamazen HI-FLASH.(TM). COLUMN size L, elution solvent: hexane/ethyl acetate) to give the title compound (333 mg). 1H-NMR (CDCl3)delta:1.25(6H,d,J=6.9 Hz), 1.51(9H,s), 2.97-3.08(2H,m), 3.95-4.16(2H,m), 4.65-4.82(2H,m), 6.51(1H,t,J=4.5 Hz), 8.34(2H,d,J=4.8 Hz). MS:237 (M++1 when tert-butyl group was cleaved).
639068-43-2 tert-Butyl 3,5-dimethylpiperazine-1-carboxylate 22219990, apiperazines compound, is more and more widely used in various fields.
