Abstract
The invention relates to a method for the preparation of 2,2,6,6-tetramethyl-4-oxopiperidine p-toluenesulphonate showing antidepression and antineurotic effect. The compound has the general formula The method consists of consecutive production of triacetonamine from acetone and gaseous ammonia. Additional quantity of acetone and a catalyst is added and the compound becomes 2,2,6,6-tetramethyl-4-oxopiperidine which, without being isolated, settles as a salt of the p-toluenesulphonic acid. 4 claims
