Procedure

To 450 mg of the compound (161) obtained in Example 39, 4 ml of concentrated hydrochloric acid and 16 ml of acetic acid were added, and the solution was heated at reflux for 7.5 hours. The solvent was removed by distillation, and crystals were filtered off and washed with ethanol and ether in this order to obtain 124 mg of the subject compound (163).
