As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 56844-40-7, name is 6-Bromothieno[2,3-d]pyrimidin-4(3H)-one, molecular formula is C6H3BrN2OS, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. HPLC of Formula: C6H3BrN2OS
General procedure: To a stirred solution of intermediate 6 (100 mg, 0.433 mmol) in DMF was added K2CO3 (179 mg, 1.299 mmol) and 3-fluorobenzyl bromide (54 muL, 0.433 mmol) at RT. After stirring for 12 h, the reaction mixture was concentrated to dryness under vacuum and the residue was extracted with CH2Cl2 and water. The organic layer was washed with brine and dried over MgSO4. Then the solution was concentrated to dryness under vacuum and puried via a ash chromatography silica gel plate (petroleum ether/ethyl acetate, 3/1) to afford title compound as a pale yellow solid in 43% yield.
With the rapid development of chemical substances, we look forward to future research findings about 56844-40-7.
