description	Intermediate compounds for the preparation of Praziquantel are provided. In particular, the intermediate compounds provided include a compound of formula (IV) and a compound of formula (V). Also provided are processes for preparing the intermediate compounds. Additionally, the raw materials are inexpensive and easy to obtain, the key intermediates are easy to prepare, and the total reaction yield and purity of the obtained target compound Praziquantel is high, so that industrialized mass production of Praziquantel using the intermediate compounds is easy to achieve.
