実験手順
In 50 ml of ethyl acetate saturated with hydrogen chloride was dissolved 2.18 g of Compound 137 obtained by Example 137, and the solution was stirred for 1 hour. Thereafter, the solvent was evaporated under reduced pressure, and the residue was recrystallized from methanol to afford 0.31 g of the desired compound (Compound 138).
