Reference of 53937-02-3 ,Some common heterocyclic compound, 53937-02-3, molecular formula is C12H11NO2, 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.
In following a method similar to that described in Katigiri, N; Sato, M.; Yoneda, N.; Saikawa, S.; Sakamoto, T.; Muto, M.; Kaneko, C. J. Chem. Soc. Perkin Trans. 1, 1289-1296, 1986, a solution of 4-benzyloxy-2-pyridone 1 (1.00 g, 5.00 mmol), benzylbromide (4.28 g, 2.97 mL, 25.0 mmol), finely powdered sodium hydroxide (1.00 g, 25.0 mmol), and tetrabutylammonium hydrogen sulfate (0.679 g, 2.00 mmol) in benzene (180 mL) was heated at reflux for 2 h and then cooled to room temperature. The reaction mixture was concentrated and the residue was partitioned between dichloromethane and water. The aqueous phase was separated and extracted with dichloromethane. The combined organic phases were washed with water and saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate, filtered, and concentrated to afford a brown solid. This solid was recrystallized from ethyl acetate to afford 1-benzyl-4-benzyloxy-2-pyridone 2 as a tan solid. MS (MH+) 292.2; Calculated 291 for C19H17NO2.
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. 53937-02-3, 4-Benzyloxy-2-(1H)-pyridone, other downstream synthetic routes, hurry up and to see.
