実験手順
To a stirred solution of 3-(2-oxo-2,3-dihydro-benzimidazol-1-yl)-propionic acid methyl ester (180 mg, 0.82 mmol) in THF (12 ml) was added [6-(tert-butyl-dimethyl-silanyloxy)-naphthalen-1-yl]-methanol (283 mg, 0.98 mmol) and triphenylphosphine (257 mg, 0.98 mmol). The DIAD (0.20 ml, 0.98 mmol) was then introduced in a dropwise manner and the resulting mixture was stirred at ambient temperature over night. Silica gel was added and the reaction mixture was concentrated to dryness. The resulting solid was purified via column chromatography (silica gel, 40% ethyl acetate/hexanes) to give 240 mg (60%) of the desired product as an oil which solidified on standing.
