실험 절차

260 mg (0.72 mmol) of the compound of Example 10A were dissolved in 5 ml of methanol, and 2.87 ml (2.87 mmol) of a 1M aqueous lithium hydroxide solution were added. The mixture was stirred at RT for 1 h and then acidified with 1N hydrochloric acid and diluted with DMSO. The entire solution was purified by preparative HLPC [Method 9]. This gave 215 mg (86% of theory) of the title compound.
