Hydrochloric Acid → HCID 15237330, compound

Participants

Reaction Steps

Lithium hydroxide hydrate (1.0 g, 0.025 mole) was added to a solution of the compound of Example 8 (4.13 g, 0.010 mole) in methanol (40 ml). Water (20 ml) Was added over 10 minutes to the reaction mixture. 1.0N hydrochloric acid (25 ml) was added slowly to the reaction mixture followed by water (50 ml) and brine (50 ml). The mixture was extracted twice with 75 ml of diethyl ether. The combined diethyl ether extracts were washed with brine (25 ml), dried over anhydrous magnesium sulfate, filtered and concentrated to an oil by a gentle flow of nitrogen gas. The product was purified by silica gel chromatography. The structure was supported by NMR, infrared spectroscopy and elemental analysis.
