Participants

Reaction Conditions

Reaction Steps

To compound (20) (1.09 g; 2.26 mmol), 6N-hydrochloric acid (5 mL) and methanol (25 mL) were added, and the resulting reaction mixture was stirred at 60° C. for 4 hours. The reaction mixture was evaporated under reduced pressure, and while there was some solvent left the mixture was made alkaline with a 5% aqueous sodium carbonate. Solids which precipitated out were separated by filtration. The resulting solids were dissolved in chloroform/methanol=3/1, insoluble matters were filtered out and the filtrate was evaporated under reduced pressure to give 0.72 g (yield: 81%) of the title compound (21).
