To a solution of 1,5-bis(4-(2-quinolylmethoxy)phenyl)-3-pentanone (2.21 g, 4 mmol), prepared as in step 3, in dioxane (15 mL) and ethanol (35 mL) was added NaBH4 (152 mg, 4 mmol) and the resulting mixture was refluxed for 30 minutes. The solution was then cooled to room temperature, acidified to pH 5 with 10% citric acid and concentrated in vacuo. To the residue was added water (50 mL) and the precipitated solid was filtered to afford 1,5-bis(4-(2-quinolylmethoxy)phenyl)-3-pentanol (2.3 g).
