One of the major reasons is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time, to discover the sequence of events that occur at the molecular level.14446-47-0, name is Thiazolidine hydrochloride, introduce a new downstream synthesis route. , 14446-47-0
A mixture of 2-(4-bromophenyl)-6-cyclobutyl-5,6,7,8-tetrahydro-4H-[1 ,3]thiazolo[4,5- ofjazepine (may be prepared as described in Example 2) (57.0mg, 0.16mmol), isothiazolidine 1 ,1 -dioxide (38.0mg, 0.31 mmol), cesium carbonate (78.0mg, 0.24mmol), tris(dibenzylideneacetone)dipalladium(0) (7.00mg, 0.00deltammol), and 4,5- bis(diphenylphosphino)-9,9-dimethyl-xanthene (Xantphos) (14.0mg, 0.024mmol) in 1 ,4- dioxane (3ml) was heated under argon at 1060C for 3 hours. The reaction was then cooled to room temperature, diluted with methanol and passed down an ion exchange cartridge (SCX) and washed with methanol and then a 2M ammonia in methanol solution. The basic fractions were then reduced and purified using silica gel chromatography, eluting with a mixture of 2M ammonia in methanol and dichloromethane (1-2.5%) to afford the product (E99); MS (ES+) m/e 404 [M+H]+.
This molecular description is the mechanism of the reaction; it describes how individual atoms, ions, or molecules interact to form particular products.If you are interested, you can also browse other articles of 5908-62-3, We look forward to the emergence of more reaction modes in the future.
