Synthetic Route of 155-10-2, 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. 155-10-2, name is 4-Amino-2-chloro-5-fluoropyrimidine, molecular formula is C4H3ClFN3, 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.
10287] 0.15 g (1.01 mmol) of 2-chloro-5-fluoropyrimi- dine-4-amine, 0.249 g (1.22 mmol) of (2-methyl-4,5,6,7- tetrahydrobenzothiophen-4-yl)ammonium chloride and 0.63 g (0.68 ml, 3.05 mol) of dicyclohexylethylamine in 2.0 ml of 1-methyl-2-pyrrolidone are heated at 180 C. in a closed cuvette in the microwave for 90 minutes (l3iotage Initiator, http://www.biotage.comlproduct-page/biotage-initiator).The crude mixture thus obtained is applied to silica gel and purified by column chromatography with heptane/ethyl acetate as mobile phase. Concentration gives 0.072 g of 5-fluoro-N2-(2-methyl-4,5,6,7-tetrahydro- 1 -benzothiophen-4-yl)pyrimidine-2,4-diamine (in waxy form) (22% yield at 85% purity).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 155-10-2, 4-Amino-2-chloro-5-fluoropyrimidine.
