Participants

Reaction Steps

The compound (0.375 g) obtained in Example 46-3 was dissolved in ethyl acetate (4.0 ml) and added with a 4 mol/l hydrogen chloride/dioxane solution (1.09 ml). The whole was stirred for 20 minutes and added with methanol (8.0 ml), followed by distillating off the solvent. The concentrate was added with chloroform and washed with a 1 mol/l sodium hydroxide aqueous solution, and the aqueous layer was extracted with chloroform. The organic layer was dried with anhydrous sodium sulfate and the solvent was distilled off, thereby obtaining a crude product (0.314 g) containing the subject compound as an amber liquid.
