Reaction Steps

N-(tert-butoxycarbonyl)-3,5-difluoro-L-phenylalanine (1) is coupled to N-methyl-N-methoxylamine using the carbodimide EDC in the presence of HOBT in DMF. The “Weinreb” amide product (m.p. 48° C.) is then treated with vinylmagnesium bromide in THF at 0° C. for 2 hr. Workup provided vinyl ketone 2 (m.p. 115° C.).
