Abstract: The present disclosure provides processes for preparing brexpiprazole. The present disclosure also provides processes for the purification of brexpiprazole. The processes for preparing and purifying brexpiprazole of the present invention provide substantial improvements over currently known methods. In certain embodiments, the conversion of Formula XI and XII to form XIII provides increased selectivity over previously reported methods. This offers increased yield and purity. The improved process for purifying brexpiprazole disclosed herein provides brexpiprazole with superior purity and is also more suitable for industrial production.

Abstract: A mobile phone comprises: a casing, a battery cover, a fastener, an elastic member and a ring. The casing has a receiving room and an opening connected to the receiving room. The battery cover is disposed on the casing removably. The fastener is movably disposed in the receiving room along a first direction and a second direction. The elastic member disposed in a bottom of the receiving room is against the fastener to provide a resilient force parallel to the first direction so as to couple the fastener and the battery cover. The ring is fastened on the casing via the opening. When the fastener is pressed, the fastener moves to the first direction to depart the battery cover from the casing. When the fastener is pushed, the fastener moves to the second direction to depart the ring from the casing.
