Analyzing the synthesis route of 4295-99-2

4295-99-2, The synthetic route of 4295-99-2 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4295-99-2,4-Cyanotetrahydro-4H-pyran,as a common compound, the synthetic route is as follows.

To a solution of tetrahydro-2H-pyran-4-carbonitrile (800 mg, 7.20 mmol) in THF (20 ml_) was added aluminum(lll) lithium deuteride at 0 C. The mixture was stirred at 0 C for 2 hr. To the stirred reaction mixture was sequentially added 300 uL of water, 900 muIota_ of 1 N NaOH and 300 muIota_ of water. The mixture was filtered through a thin layer of celite to remove the solid. The filtrate was dried over sodium sulfate, filtered off and concentrated in vacuo giving 700 mg of titled compound. LCMS (m/z): 1 18.2 [M+H]+, retention time = 0.25 min. The crude product was used directly for next step.
