Versuchsvorschrift

A mixture of Example 209A (921 mg, 5.19 mmol), 3-hydroxy-adamantane-1-carboxylic acid (1.22 g, 6.2 mmol), 1-ethyl-3-[3-(dimethylamino)propyl]-carbodiimide hydrochloride (2.0 g, 10.4 mmol), 1-hydroxybenzotriazole hydrate (846 mg, 10.4 mmol) and 4-dimethylaminopyridine (196 mg, 1.04 mmol) in pyridine (20 mL) was stirred at room temperature for 12 hours. The solvent was removed and the residue was diluted with water and extracted with ethyl acetate. The organic extract was dried (Na2SO4), filtered and concentrated Purification by flash chromatography (silica gel, 50% ethyl acetate/hexanes) afforded the title compound. MS (ESI) m/z 319 (M+H)+.
