N-3-[R.sub.1 -(phenyl)-C(=X)]-phenyl-lower-alkyl}amines having anti-inflammatory utility are prepared either by reduction of a 3-[R.sub.1 -(phenyl)-CO]-phenyl-lower-alkanoylamine; by benzoylating a phenyl-lower-alkylamine; by reaction of a 3-lithiophenyl-lower-alkylamine with a R.sub.1 -(phenyl)-carboxaldehyde, a R.sub.1 -(phenyl)lower-alkyl ketone or a R.sub.1 -(phenyl)-carbonitrile or by transformations involving manipulations of a carbonyl or carbinol group.
具有抗炎活性的N-3-[R₁-(苯基)-C(=X)]-苯基-低碳烷基}胺可以通过以下方式制备:还原3-[R₁-(苯基)-CO]-苯基-低碳烷酰胺;通过苯甲酰化苯基-低碳烷基胺;通过3-
锂代苯基-低碳烷基胺与R₁-(苯基)-甲酰
甲醛、R₁-(苯基)低碳烷基酮或R₁-(苯基)-碳
氰化物的反应;或者通过涉及羰基或
甲醇基团操作的转换过程。
