Reaction Steps
A sample of 2,3-dihydro-1'-benzyl-5-chlorospiro[benzofuran-2,4'-piperidine], free base of Example 6, is treated in a manner consistent with the procedure of Example 9 to provide the product 2,3-dihydro-5-chlorospiro[benzofuran-2,4'-piperidine]hydrochloride, mp 217°-218° C. This product is obtained after three recrystallizations, two from ethyl alcohol and then one from an ethyl alcohol-ether mixture.
