Participants

Reaction Steps

A 2 mol/L aqueous sodium hydroxide solution (5 mL, equivalent to 10 mmol sodium hydroxide) was added to an ethanol (20 mL) solution of the compound obtained in Example 30 (2.40 g, 5.5 mmol), and the mixture was stirred at room temperature for 2 hours. The solvents were distilled off, water was then added to the residue, and the aqueous solution was adjusted to a pH of 7 with a diluted hydrochloric acid. The precipitated crystals were separated by filtration and dried, to give 1.30 g (56%) of the captioned compound.
