  Synthesis and antifilarial activity of N-[4-[[4-alkoxy-3-[(dialkylamino)methyl]phenyl]amino]-2-pyrimidinyl]-N'-phenylguanidines

  摘要：

  A series of N-[4-[[4-alkoxy-3-[(dialkylamino)methyl]phenyl]amino]- 2-pyrimidinyl]-N'-phenylguanidines have been synthesized for antifilarial evaluation. Reaction of the appropriate benzenamines with N-cyanoguanidine, followed by condensation of the resultant N-phenylimidodicarbonimidic diamides (V) with ethyl 4,4,4-trifluoro-3-oxobutanoate provided the intermediate N-(4-hydroxy-2-pyrimidinyl)-N'-phenylguanidines VIa. Alternatively, compounds VIa were synthesized by reaction of the requisite beta-keto esters (VII) with N-cyanoguanidine to give the (4-hydroxy-2-pyrimidinyl)cyanamides (VIII), followed by treatment with the desired benzenamines. Chlorination with POCl3 and condensation with the appropriate benzenamines (IX) generated the desired guanidines (X). Antifilarial activity was confined to adult Litomosoides carinii infections, and a structure-activity relationship for this activity is discussed. Lack of activity against L. carinii microfilaria and adult Brugia pahangi infections preclude further work in this area pending evaluation in additional experimental models.

  To provide a process for producing a hydroxyalkyltriethylenediamine or hydroxytriethylenediamine simply and in a small number of steps without requiring multi-stage reaction steps; a novel catalyst composition whereby a polyurethane product can be obtained with good productivity and good moldability without bringing about odor problems or environmental problems; and a process for producing a polyurethane resin using the catalyst composition. For example, a hydroxyalkyltriethylenediamine or hydroxytriethylenediamine is produced by subjecting a mono-substituted dihydroxyalkylpiperazine and/or a di-substituted hydroxyalkylpiperazine to an intramolecular dehydration condensation reaction in the presence of an acid catalyst. Further, for example, a polyurethane resin is produced by using a catalyst composition which comprises a hydroxyalkyltriethylenediamine or hydroxytriethylenediamine (A), and an amine compound (B) having, in its molecule, one or more substituents selected from the group consisting of a hydroxy group, a primary amino group and a secondary amino group, or a tertiary amine compound (C) having a value of [blowing reaction rate constant/gelling reaction rate constant] of at least 0.5.
