Hydrochloric Acid → HCID 68531068, compound

Participants

Reaction Steps

The compound prepared in Example 76 (1.65 g) and (3S)-3-methyl-2-(2-oxopropyl)hexanal (1.86 g) were dissolved with tetrahydrofuran (10 mL), and 5N hydrochloric acid (0.2 mL) was added to the reaction mixture. The reaction mixture was stirred at room temperature for 6 hours. A saturated aqueous solution of sodium bicarbonate and water were added to the reaction mixture, and the reaction mixture was extracted with ethyl acetate. The obtained organic layer was washed by water and a saturated aqueous solution of sodium chloride. The organic layer was dried with anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was purified by column chromatography on silica gel (n-hexane/ethyl acetate=85/15→65/35) to obtain the title compound (1.6 g) having the following physical data.
