Hydrochloric Acid → HCID 70156400, compound

Participants

Reaction Steps

161 mg (0.338 mmol) of the compound obtained in Example 25 was dissolved in 10 ml of methanol. 0.372 ml of 1 N aqueous sodium hydroxide solution was added to the obtained solution, and they were stirred at room temperature for 4 hours. After the addition of 1 N hydrochloric acid, methanol was evaporated under reduced pressure. Water was added to the residue, and a precipitate thus formed was taken by the filtration and then recrystallized (recrystallization solvent: methanol/isopropyl ether) to obtain the title compound.
