Participants

Reaction Steps

2.32 g of the compound obtained in Step A of Example 115 in 150 ml of tetrahydrofuran are stirred for 4 hours at −30° C., under an inert atmosphere, in the presence of 15 ml of a 1M solution of ethylmagnesium bromide in tetrahydrofuran. After returning to ambient temperature, the mixture is worked up in conventional manner, then concentrated under reduced pressure, enabling the expected product to be isolated.
