Reaction Conditions

Reaction Steps

N,N-Diisopropylethylenediamine (0.79 g) was added to the intermediate (a) (2.62g) obtained in Example 28. After being stirred for 2 hours at 70° C., the reaction mixture, with chloroform added thereto, was washed with 1N sodium hydroxide aqueous solution and saturated brine successively, dried over sodium sulfate anhydride, and then filtrated. The solvent was evaporated out and the residue was purified by silica gel column chromatography (silica gel 85 g, chloroform:methanol=100:1), thereby yielding 1.45 g of the aimed compound as white solid.
