Fezolinetant preparation procedure. The present invention relates to a process for obtaining fezolinetant that allows for the production of said product with high purity and enantiomeric excess through the use of trifluoromethanesulfonic acid. The present invention also relates to the trifluoromethanesulfonic acid salt of fezolinetant and to the use of said salt in the production of fezolinetant.

The application provides a watering system and a road milling machine. The watering system comprises a water supply part, a conveying part, a watering part, a pressure regulating valve and a liquid supply part. The pressure regulating valve has an inlet, an outlet and an overflow port. The pressure regulating valve is connected to a water supply pipeline through the inlet and the outlet. The overflow port is connected to the water supply part through an overflow pipeline. The pressure regulating valve is used to adjust the water pressure of the water supply pipeline by causing water to overflow to the water supply part through the overflow pipeline. The liquid supply part is connected to the water supply pipeline through an anti-freezing pipeline. The liquid supply part is used to discharge water in the water supply pipeline and the overflow pipeline by using anti-freezing liquid and to fill the water supply pipeline and the overflow pipeline with the anti-freezing liquid. The watering system of the application uses the anti-freezing liquid to replace the water in the water supply pipeline and the system components. Before the next operation, the conveying part can be started without water injection and emptying, which reduces the preparation procedure during operation, is simple and convenient, and is beneficial to improving work efficiency.

The utility model relates to a kind of gas stove of being convenient to assemble, the stove shell of this gas stove, front plate, end plate, rear plate are integrally connected in sequence and are shaped, without separately positioning alignment to these three components, reduce the preparation procedure of early assembly;The gap between the baffle of the left and right sides of end plate and front plate, rear plate is formed, side plate can be directly inserted into gap, the quick positioning of side plate is realized, avoid the cumbersome alignment operation in traditional assembly, substantially reduce assembly difficulty, it is favorable to improve the overall assembly efficiency, after side plate is inserted into gap, by first screw and baffle connection, the fixation of side plate and other integrally formed components is initially realized;And the four corners of the lower end of side plate and front plate, rear plate are connected by second screw and reinforcing connecting plate, further improve the firmness of connection between the components of stove shell, to ensure the structural stability of stove shell whole, reduce the security risk caused by stove shell loosening, enhance the safety in the use process of gas stove.
