Abstract: Provided are a data obtaining method, an inverter, and a rotating electric machine capable of managing the operation state of a device without complicating the configuration thereof. Therefore, the data obtaining method uses an inverter for controlling a synchronous electric motor, wherein a position/speed calculation unit of the inverter calculates an electric angle of the synchronous electric motor from the value of the current flowing between the synchronous electric motor and the inverter and obtains data for each electric angle by sampling internal data within the inverter, said internal data being used for controlling the synchronous electric motor in synchronization with the information of the electric angle.

Abstract: The present invention relates to a method for producing a pyrimidine derivate useful as a neurocyte neurocyte necrosis inhibitor and an intermediate thereof. Disclosed is a method for producing an acid salt of 4-(4-fluorophenyl)-2-methyl-6-(5-piperidinopentyloxy) pyrimidine. The method comprises reacting 4-chloro-6-(4-fluorophenyl)-2-methylpyrimidine with 5-piperidino-1-pentanol, hydrating the thus obtained 4-(4-fluorophenyl)-2-mehtyl-6-(5-piperidinopentylox) pyrimidine and then converting the resultant the hydrate into an acid salt. The hydrate as a describe above; and a method for producing the hydrate is part of this invention. According to the present invention, a highly pure acid salt of 4-(4-fluorophenyl)-2-methyl-6-(5-piperidinopentyloxy) pyrimidine can be readily and efficiently produced without using a column chromatography. Thus, this method is suitable for the production thereof on a industrial scale.
