실험 절차

KR2002076486 describes a process for preparation of praziquantel by reacting phenylethylamine with chloroacetyl chloride to obtain 2-chloro-N-phenethylacetamide. The compound 2-chloro-N-phenethylacetamide is then reacted with pthalimide to give 2-pthalimido-N-phenethylacetamide, which is then treated with hydrazine monohydrate to give 2-amino-N-phenylethylacetamide. On further treatment with bromoacetal, 2-amino-N-phenylethylacetamide gives 2-[2,2-dimethoxyethyl)amino]-N-(2-phenylethyl)acetamide. This compound on further cyclization and acylation using cyclohexanoylchloride forms praziquantel.
