Reaction Steps

2.92 g of the compound (6) obtained in Example 2 (1), 1.07 g of pyrrolidine and 2.25 g of 1,8-diazabicyclo[5.4.0]-7-undecene were added to 20 ml of N,N-dimethylformamide, and the solution was heated at 80° C. for 12 hours. The solvent was removed by distillation, and 100 ml of chloroform was added to the residue. After washing with water, the organic layer was separated from the solution. After drying over magnesium sulfate, the solvent was removed by distillation. To the residue, 50 ml of isopropyl ether was added, and the solid was filtered to obtain 2.60 g of the subject compound (122).
