Procedure
To a solution of the compound obtained in Example 34 (3) (381 mg) in N,N-dimethylformamide (10 ml), copper(I) iodide (111 mg) was added and the mixture was stirred at 150° C. for 2 hours. The reaction solution was poured into water, and the mixture was extracted with chloroform, washed with water, dried over magnesium sulfate and concentrated under reduced pressure. The resulting residue was separated using silica gel preparative thin-layer chromatography (chloroform:methanol=20:1) to obtain 155 mg (40.7%) of the desired product as a yellow powder.
