109384-19-2, tert-Butyl 4-hydroxypiperidine-1-carboxylate is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
4-Fluorobenzonitrile (3. 0G) was dissolved in THF (50ML) and then N-tert-butoxy-carbonyl- 4-piperidinol (4.98g) was added. Potassium HEXAMETHYIDISILAZIDE (20% wt solution in THF, 24.62g) was then added dropwise and the reaction stirred at rt for 2h. The reaction mixture was then evaporated to a minimum, redissolved in EtOAc (100 ml) and washed with aqueous 1N HCI (2X100 ML), saturated sodium bicarbonate solution (2X100 ML) and brine (100 ML). The organic layer was dried (MGS04) and then purified by chromatography [silica gel, step gradient 0-60% EtOAc/Hexane]. Fractions containing the required product were evaporated to give the title compound (D21) as a clear oil which crystallised on standing (6.83 g).’H NMR 8 (CDCI3) : 7.59 (2H, d, J=7. 50HZ), 6.95 (2H, d, J=7. 50HZ), 4.44 (1H, m), 3.70 (2H, m), 3.38 (2H, m), 1.91 (2H, m), 1.77 (2H, m), 1.47 (9H, s).
109384-19-2, As the paragraph descriping shows that 109384-19-2 is playing an increasingly important role.
