Application of 311-86-4 ,Some common heterocyclic compound, 311-86-4, molecular formula is C3H4BrF3O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
To a mixture of 1-[1-(3-azetidin-3-yl-5-chloro-2-methoxy-4-methylphenyl)ethyl]-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine dihydrochloride (20 mg, 0.04 mmol, chiral intermediate from peak 1 of Example 1, step 7) and triethylamine (19 muL, 0.13 mmol) in acetonitrile (0.6 mL) was added 2-bromo-3,3,3-trifluoropropan-1-ol (from Synquest Labs, 9.2 mg, 0.048 mmol). N,N-dimethylformamide (0.3 mL) was added, which created a clear solution that was stirred at 70 C. overnight. The mixture was diluted water and purified using RP-HPLC (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 30 mL/min) to give 6.6 mg (30%) of the desired product. The product was isolated as a mixture of diastereomers. LCMS calculated for C22H27ClF3N6O2 (M+H)+: m/z=499.2; Found: 499.1.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 311-86-4, 2-Bromo-3,3,3-trifluoropropan-1-ol, other downstream synthetic routes, hurry up and to see.
