76176-87-9, A common heterocyclic compound, 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., 76176-87-9
To the stirred solution of [cis-3-(4-amino-5-iodo-pyrrolo [2,3-d]pyrimidin-7-yl)-cyclobutyl] methanol (Intermediate M: 348 mg, 1.0 mmol) and acetonitrile (70 mL) was added IBX (Atlantic SciTech 86900: 561 mg, 2.0 mmol, 2 eq). The reaction mixture was stirred for 1 h at 80 C. Th e reaction mixture was filtered at 40 C and the filtrate was concentrated. To the residue was added subsequently DCM (50 ml_), ethyl-diisopropyl-amine (3.43 ml_, 20 mmol, 20 eq), 1-oxide thiomorpholin hydrochloride (312 mg, 2.0 mmol, 2 eq) and sodium triacetoxyborohy- dride (637 mg, 3.0 mmol, 3 eq) with stirring at rt. The reaction mixture was stirred for 1 h at rt and then partitioned between NaHC03 1M and EtOAc. The combined organic layers were washed with water and brine, dried (Na2S04), filtered and concentrated. The residue was purified by silica gel column chromatography (DCM/MeOH/NH3aq, 200:20:1) to afford 238 mg of the title compound as pale yellow crystals: HPLC-MS: M+H = 446.2 (Rt = 0.41) (Method X); TLC; Rf = 0.26 (DCM/MeOH/NH3aq, 200:20: 1).
According to the analysis of related databases, 76176-87-9, the application of this compound in the production field has become more and more popular.
