The target p38 MAP kinase inhib­itor is a candidate for the treatment of various ­inflammatory disorders, such as rheumatoid ­arthritis, psoriasis and Crohn’s disease. It was synthesized on a multikilogram scale in eight steps from 2,6-difluoroaniline in 38% overall yield without recourse to chromatography.
