Versuchsvorschrift

To a solution of compound 5x (0.35 g, 1 mmol, obtained from the above Synthesis Example 12) in dry DMF (20 mL) was added NaH (60% in oil, 2.64 g, 66.0 mmol) at 0° C. for 1 hr. After stirring at room temperature for 8 hrs, epichlorohydrin (0.92 g, 10 mmol) was added and stirred for a further 1 hr. The reaction mixture was partitioned between H2O and CH2Cl2. The organic layer was dried over MgSO4 and concentrated. The resultant residue was purified by column chromatography (MeOH/CH2Cl2=1:10) to give the title compound 5kkk (0.33 g, 84% yield).
