111300-06-2, name is tert-Butyl (trans-4-hydroxycyclohexyl)carbamate, belongs to amides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Safety of tert-Butyl (trans-4-hydroxycyclohexyl)carbamate
(1) To a solution of tert-butyl(trans-4-hydroxycyclohexyl)carbamate (1.08 g, 5.00 mmol) and 15-crown 5 (1.04 mL, 5.25 mmol) in tetrahydrofuran was added sodium hydride (60% dispersion in mineral oil, 440 mg, 11.0 mmol) at 0 C., followed by iodomethane (0.327 mL, 5.25 mmol) at 0 C. After being stirred for 2 hour, the reaction mixture was poured into water. The mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, died over sodium sulfate, filtrated and concentrated in vacuo. The residue was purified by silica gel column chromatography to give tert-butyl(trans-4-methoxycyclohexyl)carbamate as a colorless solid (796 mg, 69%). MS (APCI): m/z 247 (M+NH4), 230 (M+H).
The synthetic route of 111300-06-2 has been constantly updated, and we look forward to future research findings.
