Procedure
1.60 g of the compound (162) obtained in Example 39 (2) was added to 20 ml of methylene chloride, and 6 ml of trifluoroacetic acid was added to the solution. The solution was stirred for 1.5 hours. 4 ml of trifluoroacetic acid was added to the solution, and the solution was stirred overnight. The solvent was removed by distillation, and the residue was crystallized from ethyl ether. Crystals were filtered off to obtain 410 mg of the subject compound (165).
