Electric Literature of 7252-83-7,Some common heterocyclic compound, 7252-83-7, name is 2-Bromo-1,1-dimethoxyethane, molecular formula is C4H9BrO2, 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.
Step 1: Synthesis of 2-chloro-7-(2,2-dimethoxyethyl)-4-morpholin-4-yl-7H-pyrrolo[2,3-d]pyrimidine To a solution of 2-chloro-4-morpholin-4-yl-7H-pyrrolo[2,3-d]pyrimidine (650 mg, 2.7 mmol) in DMF (10 mL) were added 2-bromo-1,1-dimethoxyethane (0.65 mL, 5.4 mmol) and Cs2CO3 (1.067 g, 3.3 mmol). The resulting mixture was heated at 80 C. under nitrogen overnight, and cooled to room temperature. Water was added, and the mixture was extracted with EtOAc. The combined extracts were washed with water and brine, dried over MgSO4. The solvent was removed under reduced pressure to give the title compound as light yellow solid (665 mg, 75% yield), which was used in next step without further purification. MS(ESI) m/z 327.2.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Bromo-1,1-dimethoxyethane, its application will become more common.
