Procedure

To a solution of 0.3 g (0.7 mmol) of material from Example 45 in 4 mL of tetrahydrofuran at ambient temperature was added 0.5 mL (1.5 mmol) of a 3.0M solution of ethylmagnesium bromide in ethyl ether. The mixture was stirred for 16 hours, diluted with 5 mL of half saturated brine and extracted four times with 5 mL each of ethyl acetate. The combined organics were dried (MgSO4), filtered and concentrated in vacuo. Chromatography (15 g silica gel, 50% ethyl acetate/hexane) of the residue afforded 0.1 g (42%) of the title compound.
