Sodium methanolate methanol → HCID 90384391, compound

Participants

Reaction Steps

The compound (489 mg, 1.50 mmol) of Step 1 of Example 54 was dissolved in methanol (7 mL), and a 25% sodium methoxide methanol solution (1.5 mL) were added thereto, and heated under reflux for 3 hours. The resultant was returned to room temperature, and the solvent was distilled away under reduced pressure. The resulting residue was diluted with ethyl acetate, washed with water and saturated brine, and then dried over anhydrous magnesium sulfate. The solvent was distilled away under reduced pressure. The resulting residue was purified by silica gel chromatography (hexane/ethyl acetate) to thus obtain the title compound.
