278788-66-2, (R)-tert-Butyl 3-(hydroxymethyl)piperazine-1-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Tert-butyl (R)-3-(hydroxymethyl)piperazine-1-carboxylate (384 mg, 1.78 mmol) was added to a mixture of 53 7-bromo-4,6-dichloro-3-nitroquinoline (260 mg, 0.81 mmol) and 56 DIPEA (0.316 ml, 1.78 mmol) in NMP (4 ml). The mixture was heated at 75 C. for 2 hours, then allowed to cool to room temperature. The mixture was partitioned between ethyl acetate (100 ml) and water (100 ml). The aqueous layer was extracted with ethyl acetate (100 ml) and the extracts combined with the organic layer. The combined organics were washed sequentially with water (2×100 ml) and saturated brine (50 ml), then dried and evaporated to dryness to give a brown gum. The crude product was purified by flash silica chromatography, elution gradient 20 to 40% 57 EtOAc in 58 heptane. Pure fractions were evaporated to dryness to afford 59 tert-butyl (R)-4-(7-bromo-6-chloro-3-nitroquinolin-4-yl)-3-(hydroxymethyl)piperazine-1-carboxylate (218 mg, 54%) as a yellow solid. 1H NMR (500 MHz, DMSO, 27 C.) 1.43 (9H, s), 3.34-3.53 (5H, m), 3.64 (3H, d), 4.34-4.42 (1H, m), 4.58 (1H, t), 8.38 (1H, d), 8.49 (1H, s), 9.05 (1H, s). m/z: ES+ [M+H]+ 501.
278788-66-2, 278788-66-2 (R)-tert-Butyl 3-(hydroxymethyl)piperazine-1-carboxylate 24820286, apiperazines compound, is more and more widely used in various fields.
