Reaction Steps

To magnesium turnings (4.27 g) in tetrahydrofuran (56 ml) was added a solution of bromoethane (19 g) in THF (19 ml) over 5 hours. To this slurry at 0° C. was added a solution of the product of part (i) (24 g) in 1,2-dimethoxyethane (70 ml) over 1 hour. The reaction was quenched at 10° C. using glacial acetic acid (10 g) to give a solution of the title compound which was used directly in the next step.
