N-(2-Hexahydropyrimidinoethyl) anilines (6a-f) were prepared by the condensation of N-(β-bromoethyl) aniline hydrobromide and hexahydropyrimidines. They were further converted to N-(2-hexahydropyrimidinoethyl) propionanilides by N-propionylation. The analgesic activities of the twelve compounds thus obtained were examined by subcutaneous administration to mice. Among the propionanilides, the N-isopropyl- and N-benzylhexahydropyrimidine derivatives (7c, e) possessed ca. 1/3 and 1/6 of the analgesic effect of pentazocine, respectively, and 7e showed a lower toxicity. On the other hand, the N-phenethyl derivative (7f) was inactive.
