実験手順

2.6 g (7.46 mmol) (S)—N-(1-{4-[3-(tert-Butyl-dimethyl-silanyloxy)-azetidin-1-yl]-phenyl}-ethyl)-acetamide (IV.1) are added to 20 mL THF and the mixture is cooled to 5° C. 14.9 mL (14.9 mmol) tetrabutylammonium fluoride (1 N in THF) are added and the mixture is allowed to warm to rt. Stirring is continued for 1 h and the solvent is removed in vacuo. The residue is purified by column chromatography (silica gel; DCM:MeOH; gradient 9:1→8:2) to yield the desired product.
