반응 단계
A solution of the product of Example 44B (2.8 g, 11.5 mmoles), sodium chloride (1.3 g, 22.9 mmoles) and water (0.4 ml, 22.9 mmoles) in dimethyl sulfoxide (48.0 ml) was stirred at about 180° C. for about 30 min. The mixture was cooled, diluted with water (100.0 ml) and was extracted twice with (1:1) ethyl acetate/diethyl ether (80.0 ml each). The combined organic extracts were washed with brine, dried over MgSO4, filtered and concentrated in vacuum. The crude product was purified by flash column chromatography on silica gel using hexanes/ethyl acetate (2:1) as the mobile phase to provide the title compound.
