4-Bromomethypiperidine-1-carboxylic acid tert-butyl ester Usage And Synthesis
Uses4-Bromomethypiperidine-1-carboxylic acid tert-butyl ester can be used as organic synthesis intermediate and pharmaceutical intermediate, mainly in laboratory research and development process and chemical production process.
SynthesisSynthesis_158407-04-6
4-Bromomethypiperidine-1-carboxylic acid tert-butyl ester. 4-N-Boc-piperidine-methanol (200 mg, 0.93 mmol) was dissolved in diethyl ether (9 mL) and carbon tetrabromide (370 mg, 1.1 mmol) and PPh3 (292 mg, 1.1 mmol) were added at rt. The reaction was allowed to stir for 18 h at rt and filtered over a pad of celite. The filtrate was concentrated and purified by flash chromatography (hexane/EtOAc, 1:0 ú 4:1) to give the title compound. Yield 55 mg. 1 (400 MHz, DMSO-d6) | ppm 4.02-3.98 (m, 2 H), 3.47 (d, 2 H), 2.78-2.65 (m, 2 H), 1.89-1.74 (m, 3 H), 1.45 (s, 9 H), 1.12-0.98 (m, 2 H).
