With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.10397-13-4, name is 4-(4,6-Dichloropyrimidin-2-yl)morpholine, molecular formula is C8H9Cl2N3O, molecular weight is 234.08, as common compound, the synthetic route is as follows.Safety of 4-(4,6-Dichloropyrimidin-2-yl)morpholine
Step 1: A mixture of 2,2-dimethylmorpholine (2.0 equiv.), 4-(4,6-dichloropyrimidin-2-yl)morpholine (1 equiv.) and triethylamine (6 equiv.) in EtOH (0.2 M) were heated to 110 C. for 25 min in the microwave. The reaction mixture was partitioned between EtOAc and water. The organic phase was dried over sodium sulfate. The resulting solution was concentrated and dried under vacuo to give 4-(6-chloro-2-morpholinopyrimidin-4-yl)-2,2-dimethylmorpholine and was used in the next step without further purification. LCMS (m/z) (M+H)=313.2, Rt=0.86 min.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,10397-13-4, 4-(4,6-Dichloropyrimidin-2-yl)morpholine, and friends who are interested can also refer to it.
