反応手順
Benzyl 2-isopropyl-4-oxopiperidine-1-carboxylate, prepared as described for compound 67 in Example 3 using isopropylmagnesium chloride, was formylated and treated with hydrazine hydrate as described for compound 50 in Example 1 to give benzyl 6-isopropyl-6,7-dihydro-1H-pyrazolo[4,3-c]pyridine-5(4H)-carboxylate. This compound was then deprotected and treated with 4-chlorophenylsulfonyl chloride followed by NaOH as described for compound 52 in Example 1.
