After that,
The solution is washed three times with 100 ml of 1N hydrochloric acid, twice with 100 ml of 5% sodium bicarbonate, and five times with 50 ml of water, and then dried over anhydrous sodium sulfate. After removing the sodium sulfate, the liquid was concentrated under reduced pressure to reduce the concentration residue to 0.
