Synthetic Route of 1190380-49-4, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1190380-49-4, name is 1-(Tetrahydro-2H-pyran-4-yl)-1H-pyrazol-4-amine, This compound has unique chemical properties. The synthetic route is as follows.
1-(Oxan-4-yl)-1 H-pyrazol-4-amine (51 mg, 0.303mmol) was added to a solution of A7 (59mg, 0.151 mmol) in dioxane (2mL). The reaction mixture was stirred at 70C for 17h. The mixture was diluted with EtOAc (30ml_) and was washed with sat aq NaHC03 (2 x 10ml_) and brine (2 x 10ml_) before drying over MgS04 and cone, in vacuo. The crude reaction mixture was purified by preparative TLC on silica, eluting with 5% MeOH/10% iPr20/CH2CI2 to give the title compound as a white solid (19mg, 26%). 1H NMR (500MHz, CDCI3 + 1 drop DMSO-d6) 8.52-8.50 (1 H, m), 8.31-8.11 (1 H, m), 7.97-7.92 (1 H, m), 7.62 (1 H, s), 7.27-7.20 (4H, m), 5.83-5.65 (2H, m), 4.40-4-27 (1 H, m), 4.18-4.08 (2H, m), 3.76-3.62 (2H, m), 3.61-3.48 (2H, m), 3.18-3.04 (3H, m), 2.15-2.03 (5H, m). LCMS (Method 1 ) Rt 1 .883min. ESIMS m/z [M+H]+ 475.2.
The chemical industry reduces the impact on the environment during synthesis 1-(Tetrahydro-2H-pyran-4-yl)-1H-pyrazol-4-amine. I believe this compound will play a more active role in future production and life.
