Following a procedure similar to that described in Example 67(c), but using N-[4-(4-dimethylaminomethyl-2-pyridyloxy)-cis-2-butenyl]-2-(2-hydroxyethylthio)acetamide [prepared as described in step (a) above] and acetic anhydride as starting materials, in relative proportions similar to those used in that Example, the title compound was obtained in a 58% yield.
