This contribution describes the initial preparation of two potent β-3 receptor agonists 1 and 2. Subsequent scale up of these two compounds was required for further evaluation and proceeded via a common key amine intermediate 24. Synthesis of this key intermediate by way of a Ritter reaction was a vital step in the sequence. Enantioselective Noyori hydrogenation reactions gave access to the chiral
