Tertiary carbinamine 5 is an isolated intermediate in the synthesis of a novel, inhaled β-2 adrenoreceptor agonist PF-610355. Process development for the key amide-formation and Ritter reactions, together with reaction understanding studies are discussed in context of the synthesis of 5. The optimized process employed to manufacture 140 kg of 5 is described, and was shown to have superior metrics to the preliminary commercial route.
