Reaction Steps

5.1 g of the compound (30) obtained in Example 5 (1) was dissolved in 110 ml of acetic acid, and then 25 ml of concentrated hydrochloric acid was added to the solution. The solution was stirred overnight at room temperature. The crystal was filtered off and washed successively with ethanol and ether to obtain 4.6 g of crude crystal. The filtrate was removed by distillation, and 80 ml of ethanol was added to the residue, and the deposited crystal was filtered off. The combined crude crystal was recrystallized from ethanol to obtain 4.61 g of the subject compound (77). The result of the analysis of this compound was as follows.
