The initial route used to prepare PF-00610355 (8) for early clinical development is described. Through careful choice of solvent, an efficient, telescoped route to carboxylic acid 23 was developed, affording this late-stage intermediate in 80% yield over 4 steps. Deprotection of 23 to give sodium salt 24a and coupling with amine 6·HCl afforded the desired API. Effective synthetic routes to two of the starting materials, chiral bromide 1 and amine 6, are also described.
