The development of a factory process to manufacture the novel cardiac myosin activator omecamtiv mecarbil (1) is described. Omecamtiv mecarbil is prepared via the convergent synthesis and coupling of two key fragments, aniline 2 and carbamate 4-HCl, which serves as a masked isocyanate. To enable practical access to aniline 2, reduction of the corresponding nitroaromatic was designed to control potential mutagenic impurities. Key to the efficient preparation of 2 was the benzylic bromination of 8 followed by selective debromination of a gem-dibromide byproduct and subsequent alkylation with 5-phosphate. Overall, the longest linear sequence consists of six steps, including a final salt formation step to afford the drug substance in 55% overall yield. Because of poor performance of the original free-base form of the drug substance in modified-release formulations, an improved dihydrochloride hydrate form was developed to aid drug product performance and manufacturability.

Optimization of a series of aminomethyl ketone diamine H3R antagonists to reduce the brain exposure by lowering the pKa, led to molecules with improved pharmacokinetic properties. Compounds 9, 19, and 25 had high affinity for human H3R and demonstrated in vivo H3R functional activity in the rat dipsogenia model. Compound 9 displayed modest wake-promoting activity in the rat EEG/EMG model.

supporting information; experimental part, p. 6420 - 6431 (2012/09/05)
An efficient and general method for the synthesis of unsymmetrical tetrasubstituted ureas from carbamoylimidazole is described. The conversion is achieved by the concurrent quarternization of the imidazole nitrogen and activation of amines with AlMe3. The Royal Society of Chemistry 2012.

scheme or table, p. 472 - 477 (2011/03/20)
We report the design, synthesis, and optimization of the first, selective activators of cardiac myosin. Starting with a poorly soluble, nitro-aromatic hit compound (1), potent, selective, and soluble myosin activators were designed culminating in the discovery of omecamtiv mecarbil (24). Compound 24 is currently in clinical trials for the treatment of systolic heart failure.
