Reaction Conditions

Reaction Steps

To the compound (98.8 mg, 0.400 mmol) of Step 1 of Example 21, NBS (78.3 mg, 0.440 mmol), and a catalytic amount of BPO, carbon tetrachloride (4 mL) was added, and heated under reflux overnight. The resultant was returned to room temperature, and the solvent was distilled away under reduced pressure. The resulting residue was diluted with dichloromethane, washed with a saturated aqueous sodium hydrogen carbonate solution and saturated brine, and then dried over anhydrous magnesium sulfate. The solvent was distilled away under reduced pressure. The resulting residue was dissolved in acetonitrile (2 mL), and sodium cyanide (39.2 mg, 0.800 mmol) and water (0.2 mL) were added thereto, and stirred at 50° C. for 30 minutes. To the reaction solution, a 1 N sodium hydroxide aqueous solution was added. After concentrated under reduced pressure, the resultant was diluted with ethyl acetate, washed with water and saturated brine, and then dried over anhydrous magnesium sulfate. The solvent was distilled away under reduced pressure. The resulting residue was purified by silica gel chromatography to thus obtain the title compound.
