Reaction Steps
This material was prepared from 1-benzhydryl-3-azetidinol (1) (1.12 g, 4.7 mmol) and 2-(trifluoromethyl)-4′-(difluoromethoxy)benzhydrol (173) (3.0 g, 9.4 mmol) using the procedure described for compound (3). After basic aqueous workup, the crude product was partially purified by flash column chromatography [SiO2; ethyl acetate-iso-hexane (10:90-+15:85)] to afford an amber gum (2.83 g) which was used directly in the next step without further purification.
