This material was prepared from 1-benzhydryl-3-azetidinol (1) (7.5 mmol) and 2-(trifluoromethyl)-4′-methoxybenzhydrol (155) (15 mmol) using the procedure described for compound (3). Flash column chromatography [SiO2; ethyl acetate-iso-hexane (10:90→20:80)] afforded a pale yellow gum (2.73 g) which was used in the next step without further purification.
