Versuchsvorschrift

6-(4-Chlorophenyl)-5-(4-chlorophenylsulfonyl)-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine Benzyl 2-(4-chlorophenyl)-4-oxopiperidine-1-carboxylate, 67, was formylated and treated with hydrazine hydrate as described for compounds 50 and 51 in Example 1 to give benzyl 6-(4-chlorophenyl)-6,7-dihydro-1H-pyrazolo[4,3-c]pyridine-5(4H)-carboxylate which was then deprotected and sulfonylated as described for compound 84 in Example 7.
