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. 13223-25-1, name is 2-Chloro-4,6-dimethoxypyrimidine, molecular formula is C6H7ClN2O2, 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. COA of Formula: C6H7ClN2O2
Step 5) 4,6-dimethoxy-2-(piperazin-l-yl)pyrimidine To a mixture of 2-chloro-4,6-dimethoxypyrimidine (1.26 g, 7.2 mmol) in DMF (10 mL) were added potassium carbonate (1.00 g, 7.2 mmol) and anhydrous piperazine (1.24 g, 14.4 mmol). The reaction mixture was heated to 100 C and stirred for 10 hours. Then the reaction mixture was cooled to rt, diluted with water (10 mL) and extracted with EtOAc (20 mL x 3). The combined organic phases were dried over anhydrous Na2S04, filtered and concentrated in vacuo. The residue was purified by silica gel column chromatography (CLLC /MeOH (v/v) = 20/1) to give the title compound as yellow oil (1.05 g, 65.0%). The compound was characterized by the following spectroscopic data: LC-MS (ESI, pos. ion) m/z: 225.1 [M + H]+ and lH NMR (CDC13, 400 MHz) delta (ppm): 5.39 (s, 1H), 3.86 (s, 6H), 3.78 (t, J= 4.9 Hz, 4H), 3.47 (t, J = 5.0 Hz, 4H).
With the rapid development of chemical substances, we look forward to future research findings about 13223-25-1.
