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.

This invention relates to compounds having structural Formula (I); and pharmaceutically acceptable salts thereof which are inhibitors of the Renal Outer Medullary Potassium (ROMK) channel (Kir 1.1). The compounds of Formula I are useful as diuretics and natriuretics and therefore are useful for the therapy and prophylaxis of disorders resulting from excessive salt and water retention, including cardiovascular diseases such as hypertension and chronic and acute heart failure.
