25850-22-0, 2,2-Dimethyltetrahydro-2H-pyran-4-amine is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
The 4-chloro-3-nitroquinoline-6-carbonitrile (4.74 g, 17.55 mmol) was suspended in MeCN (50 mL) then 2,2-dimethyltetrahydro-2H-pyran-4-amine (2.49 g, 19.3 mmol) was added, after the DIEA (4.54 g, 35.1 mmol) was added the mixture was stirred at 20C for 2h, turning brown to tan. LCMS indicated complete conversion to the desired product. The mixture was concentrated under vacuum, the residue was purified by silica gel column chromatography (PE/EtOAc = 1/1) to give the desired product (4.88 g, 85% yield) as yellow solid. The purity and structure of the product were confirmed by LCMS and 1HNMR. LCMS: RT 0.73 mm, MS 327.0) 1H NMR (400 MHz, DMSO-d6) O 9.09 (5,1H), 9.02 (5, 1H), 8.42 (d, J= 8.4 Hz, 1H), 8.15(dd, J= 8.6, 1.6 Hz, 1H), 8.01 (d, J= 8.6Hz, 1H), 3.98 (m, 1H), 3.76-3.66 (m, 1H), 3.60 (td, J = 12.2, 2.3 Hz, 1H), 2.01 (ddd, J =12.6, 4.6, 2.6 Hz, 1H), 1.93-1.82 (m, 1H), 1.67 (m, 1H), 1.56 (t, J = 12.3 Hz, 1H), 1.19(d, J = 7.7 Hz, 6H)., 25850-22-0
25850-22-0 2,2-Dimethyltetrahydro-2H-pyran-4-amine 3809203, aTetrahydropyrans compound, is more and more widely used in various fields.
