Conditions

Temperature: 90 °C

Procedure

A mixture of 4.3 parts of 1-(4-chlorobutoxy)-4-methoxybenzene, 6.6 parts of N-(phenylmethyl)-N-(4-piperidinyl)-2-benzothiazolamine (Z)-2-butenedioate(1:1), 5.3 parts of sodium carbonate, 0.1 parts of potassium iodide and 90 parts of N,N-dimethylacetamide was stirred overnight at 90° C. The reaction mixture was poured onto water. The product was extracted with methylbenzene. The extract was washed with water, dried, filtered and evaporated. The residue was converted into the (E)-2-butenedioate salt in ethanol. The salt was filtered off and dried, yielding 5.6 parts (60%) of N-[1-[4-(4-methoxyphenoxy)butyl]-4-piperidinyl]-N-(phenylmethyl)-2-benzothiazolamine (E)-2-butenedioate(1:1); mp. 178.2° C. (181).
