Abstract: The present application relates to a method (I) for preparing a brivaracetam intermediate, comprising the steps of dissolving the compound represented by B-P and 1S,2S-diphenylethylenediamine in a solvent for resolution, crystallizing, filtering, and recrystallizing to obtain the compound represented by B-Q, which is then converted to the brivaracetam intermediate represented by B-R. This method can effectively resolve the compound represented by B-P. The present application also provides a method for preparing brivaracetam using the compound represented by B-R. The method can separate the effective components only through simple steps such as extraction, washing, drying, and concentration without requiring use of chiral chromatography column to separate isomers in the preparation process, and thus the separation process is simple, greatly reducing the production cost of brivaracetam.

Abstract: Positioning method and apparatus provide two services: a first, common positioning service and a second, high-precision positioning service to an upper-layer application through permission control and an independent reporting channel design. For a common application, a positioning result can be reported with a first, common precision through a common reporting channel. For a high-precision application, a positioning result with a higher level of precision can be reported through a high-precision reporting channel. In this way, the channel for obtaining the positioning result by the common application is isolated from the channel for obtaining the positioning result by the high-precision application, thus improving output security of the high-precision positioning result and satisfying security requirements of different countries or regions.
