Procedure

To 100 ml of methanol, while cooling on ice, 9 ml of thionyl chloride was added, and the solution was stirred for 30 minutes at the same temperature. 2.60 g of the compound (166) obtained in Example 43 was added to the solution, and the solution was heated at reflux for 24 hours. After air-cooling, insoluble matter was removed by filtering, and the filtrate was removed by distillation. To the residue, chloroform was added, and the formed solid matter was filtered off to obtain 2.20 g of the subject compound (167).
