The development of a practical synthesis for a p38 kinase inhibitor is described. The key advances include an improved route to the key intermediate, a substituted pyrrole, and a subsequent animation utilizing O-(4-nitrobenzoyl)- hydroxylamine, which provides a safe, scalable, and robust amination method. The new protocol was successfully demonstrated to generate 1.6 kg of API in seven steps and 26% overall yield.

A novel structural class of p38 mitogen-activated protein (MAP) kinase inhibitors consisting of substituted 4-(phenylamino)-pyrrolo[2,1-f][1,2,4] triazines has been discovered. An initial subdeck screen revealed that the oxindole-pyrrolo[2,1-f][1,2,4]tria
