A facile and improved route for the synthesis of the orally active spiroindoline-based growth hormone secretagogue, MK-677 was described. The key step adopted the Fischer indole/reduction strategy. The preparation of the key intermediates N-protected piperidine carboxaldehyde 5 and the N-Boc-O-benzyl-d-serine (2) are also optimized.

The preparation of the Merck Growth Hormone Secretagogue; MK-677 is described. A Fischer indole/reduction based strategy provides the novel spiroindoline nucleus of this potent compound. This optimized sequence necessitates the isolation of only one intermediate 10 and provides MK-677 in 48% overall yield from isonipecotic acid 3.
