Procedure

1 ml of pyrrolidine was added to 30 mg of (6-methoxy-2-cyclopentylbenzo[b]thien-3-yl)[4-(2-chloroethoxy)phenyl]methanone, followed by reflux with heating for 1 hour. The mixture was concentrated under reduced pressure to distil off pyrrolidine, and the residue was purified by TLC (developing solvent, chloroform:methanol= 19:1) to obtain 28 mg of (6-methoxy-2-cyclopentylbenzo[b]thien-3-yl)[4-[2-(1-pyrrolidinyl)ethoxy]phenyl]methanone.
