Procedure

A solution of 427 parts of N-methyl-N-(4-piperidinyl)-2-benzothiazolamine dihydrobromide monohydrate in 1500 parts of water was treated with a sodium hydroxide solution 50%. The product was extracted twice with trichloromethane. The combined organic layers were washed with water, dried, filtered and evaporated. The residue was crystallized from 490 parts of 2,2'-oxybispropane. The product was filtered off and dried, yielding 248 parts (100%) of N-methyl-N-(4-piperidinyl)-2-benzothiazolamine; mp. 86.9° C. (68).
