Versuchsvorschrift

To a solution of intermediate (16) (0.045 g, 0.088 mmol) and imidazole (0.0252 g, 0.366 mmol) in dry pyridine (1 mL) was added tert-butyl-diphenylsilyl chloride (97 μL, 0.366 mmol) at 20° C. and the reaction mixture was stirred for 48 hours. Water (30 mL) and diethyl ether (30 mL) were added and the mixture was neutralized to pH=6 using a 1 N hydrogen chloride solution. The aqueous layer was extracted with diethyl ether and the combined organic layers were dried over anhydrous MgSO4. The solvent was removed under reduced pressure and the residue was purified over silica (isooctane/ethyl acetate, 98:2) and then used directly in the next step.
