Procedure
The title compound was prepared from 6-methoxy-2-[4-[2-(1-pyrrolidinyl)ethoxy]phenyl]benzo[b]thiophene (Example 1, Part B) and 6-chloronicotinic acid in 51% yield (based on 6-methoxy-2-[4-[2-(1-pyrrolidinyl)ethoxy]phenyl]benzo[b]thiophene) by essentially following the procedures described in Example 1, Part C.
