Reaction Steps

A mixture of 21 parts of cis-1-benzoyl-4-(1H-indol-3-yl)-3-methylpiperidine, 60 parts of potassium hydroxide 385 parts of 1,2-ethanediol and 80 parts of water was stirred and refluxed (about 130° C.) overnight. After cooling for a while, about 200 parts of water were added whereupon the product was crystallized. The whole was further cooled and the solid product was filtered off, washed with a lot of water and with 2,2'-oxybispropane and dried, yielding 11.2 parts (80%) of cis-3-(3-methyl-4-piperidinyl)-1H-indole (intermediate 23).
