Secondary aliphatic-aromatic amines were synthesized by hydrogenative amination of aliphatic aldehydes with aromatic amines. The kinetics of arylsulfonation of the resulting alkylarylamines with benzenesulfonyl chloride and its monosubstituted derivatives in 2-propanol at 298 K were studied. The activation parameters of the reaction of ring-substituted N-isobutylanilines with 3-nitrobenzenesulfonyl chloride were determined.

Abstract A one-pot, simple, selective, and efficient protocol for the synthesis of aromatic secondary amines from various nitro arenes and nitriles in the presence of 10% Pd/C catalyst under H2 at atmosphericpressure and ambient temperature in tetrahydrofuran is illustrated. The scope and limitations of this method have been examined.

chelating alkylphosphines for the amination of heteroaryl and aryl chlorides, bromides, and iodides. In the presence of this catalyst, aryl and heteroarylchlorides, bromides, and iodides react with many primary amines in high yields with part-per-million quantities of palladium precursor and ligand. Many reactions of primary amines with both heteroaryl and aryl chlorides, bromides, and iodides occur to
application for the treatment of skin diseases. These efforts culminated in the discovery of N‐(2,4‐dimethylphenyl)‐N‐isobutyl‐2‐oxo‐1‐[(tetrahydro‐2H‐pyran‐4‐yl)methyl]‐2,3‐dihydro‐1H‐benzo[d]imidazole‐5‐sulfonamide (CD12681), a potent inverse agonist with in vivo activity in an IL‐23‐induced mouse skin inflammation model.
视黄酸受体相关的孤儿受体RORγ可能对多种自身免疫性疾病有潜在影响,已成为制药行业的抢手目标。本文描述了鉴定与局部应用治疗皮肤疾病相容的有效RORγ反向激动剂的努力。这些努力最终导致发现了N-(2,4-二甲基苯基)-N-异丁基-2-氧代-1-[[(四氢-2 H-吡喃-4-基)甲基] -2,3-二氢-1 H-苯并[ d ]咪唑-5-磺酰胺(CD12681),一种有效的反向激动剂,在IL-23诱导的小鼠皮肤炎症模型中具有体内活性。
