Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 956034-07-4, name is 2,4-Dichlorofuro[3,2-d]pyrimidine. A new synthetic method of this compound is introduced below., category: pyrimidines
2,4-Dichlorofuro[3,2-d]pyrimidine 37 (23 mg, 1.0 eq) was suspended in methanol (1.7 ml) and treated with morpholine (0.09 ml, 4.0 eq). Reaction mixture was stirred at room temperature for 2 h, before being quenched with saturated aq. NaHCO3. Mixture was extracted with dichloromethane. The combined organic layers were dried (Na2SO4) and concentrated to yield 2-chloro-4-morpholinofuro[3,2-d]pyrimidine 38 (14 mg, 48%) which was used in the next reaction without further purification.
