One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Recommanded Product: 2,5-Dichlorobenzooxazole, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 3621-81-6, Name is 2,5-Dichlorobenzooxazole, molecular formula is C7H3Cl2NO
5-chloro-2 – [5 – (R)-methyl -1,4-diazepan-1 -] phenyltheophylline diozaiole method for the preparation of (by machine translation)
The invention relates to 5-chloro-2 – [5 – (R)-methyl -1,4-diazepan-1 -] phenyltheophylline diozaiole method for preparing, the method comprising reducing the compound of formula I the step of shows. The invention also relates to new shown in formula I the intermediate compound. 5-chloro-2 – [5 – (R)-methyl -1,4-diazepan-1 -] phenyltheophylline diozaiole used for the treatment of sleep disorders is an important intermediate for pharmaceutical Suvorexant. The preparation method of this invention from an initial raw material is introduced to the chiral center, in the process of the whole reaction, the reaction with chiral center will be affected and reagent, avoid the chiral resolution or chiral catalyst, the cost is high, the method of low yield, the participation of there are no chiral in process reaction, the chiral purity of the product, only by using a conventional method and apparatus, the operation is simple, mild condition, route is short, high yield, is suitable for industrial production.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 2,5-Dichlorobenzooxazole, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 3621-81-6, in my other articles.
