Hydrochloric Acid → HCID 70156938, compound

Participants

Reaction Steps

The filtrate and the remainder of the solid from Example 82 were dissolved in water (100 ml)/methanol (100 ml), and neutralized with 20 ml of 0.1 mol/l hydrochloric acid. Methanol was evaporated and impurities were removed by extraction with ethyl acetate. The aqueous layer was filtered to remove insoluble components, concentrated to about 50 ml, and then allowed to stand overnight. The precipitated solid was filtered, washed with a small amount of acetone, and then dried by heating under reduced pressure to give the compound of interest (102 mg, 19%) as a pale yellow solid.
