101691-65-0, (Tetrahydro-2H-pyran-4-yl)methyl 4-methylbenzenesulfonate is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A mixture of sodium hydride (60 wt.% in mineral oil, 15.74 mg) in DMF (0.7 mL) was added to a solution of tert-butyl 2-chloro-5-(5-chloro-2-fluoropyridin-4-yl)phenylcarbamate (213 mg, 0.596 mmol) in DMF (0.70 mL) at 0 C. The resulting mixture was stirred at 0 C for 30 min. To this stirred mixture was then added (tetrahydro-2H-pyran-4-yl)methyl 4- methylbenzenesulfonate (161 mg, 0.596 mmol) in one portion. The mixture was warmed to 40 C and maintained at this temperature for 16 hrs. The reaction mixture was diluted with EtOAc, washed with IN aqueous sodium hydroxide solution, water and brine, dried over sodium sulfate, filtered off and concentrated under reduced pressure. The residue was purified by preparative TLC [silica gel, 1 mm; EtO Ac/heptane = 15/85] providing [2-chloro-5-(5-chloro-2-fluoro- pyridin-4-yl)-phenyl]-(tetrahydro-pyran-4-ylmethyl)-carbamic acid tert-butyl ester (176 mg) as a colorless oil. LCMS (m/z): 355.0/356.9 [M+H, loss of t-Bu]; Retention time = 1.21 min., 101691-65-0
The synthetic route of 101691-65-0 has been constantly updated, and we look forward to future research findings.
