125552-89-8, 4-(Bromomethyl)tetrahydropyran is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A mixture of 1H-indazole-5-sulfonic acid (2-chloromethyl-3-hydroxypropyl)(4-ethylphenyl)amide (1.26 g; 0.64 mmol), cesium carbonate (0.31 mg; 0.96 mmol) and 4-(bromomethyl)tetrahydropyran (100 mul; 0.76 mmol) in N-methyl-2-pyrrolidone (4 ml) is stirred for 1 hour at a temperature of 80 C. The reaction medium is diluted with ethyl acetate (20 ml). The organic phase is washed with saturated NH4Cl solution, with saturated NaHCO3 solution and with water. The organic phase is dried (MgSO4), filtered and concentrated. The crude product is purified by preparative HPLC (C18 column, eluent: acetonitrile in water/0.1% of formic acid). The 1-(tetrahydropyran-4-ylmethyl)-1H-indazole-5-sulfonic acid (3-chloro-2-hydroxymethylpropyl)(4-ethylphenyl)amide (100 mg; 31%) is obtained in the form of a colorless oil. 1H NMR (DMSO-d6) delta: 1.18 (t, J=7.6 Hz, 3H), 1.25-1.43 (m, 4H), 1.73 (p, J=6.4 Hz, 1H), 2.61 (q, J=7.6 Hz, 2H), 3.23 (td, J=11.3, 3.0 Hz, 2H), 3.35-3.41 (m, 1H), 3.46-3.52 (m, 1H), 3.52-3.63 (m, 2H), 3.69 (qd, J=10.8, 4.9 Hz, 2H), 3.82 (ddd, J=11.4, 4.3, 2.2 Hz, 2H), 4.39 (d, J=7.0 Hz, 2H), 4.69 (t, J=5.1 Hz, 1H), 6.95-7.02 (m, 2H), 7.16-7.22 (m, 2H), 7.44 (dd, J=9.0, 1.8 Hz, 1H), 7.92 (d, J=8.9 Hz, 1H), 8.10 (d, J=1.6 Hz, 1H), 8.31 (s, 1H). MS: [M+H]=506, 125552-89-8
The synthetic route of 125552-89-8 has been constantly updated, and we look forward to future research findings.
