Procedure
A solution of compound 9 (0.238 g) in ethyl acetate (2 ml) and methanol (4 ml), under cooling to a solution, was treated with HCl gas in ethyl ether dropwise to adjust the pH 5.0, then concentrated in vacuo. The concentrate was crystallized with ethyl acetate. The resulting precipitate was collected by filtration, and was recrystallized with ethyl acetate. Compound 10 was obtained as a pale yellow crystal(0.172 g).
