Procedure

In a 10 mL round-bottom flask, 1-Allyl-1H-indole-5-carbaldehyde (169 mg, 0.91 mmol) is dissolved in 0.5 mL of anhydrous THF. To this solution is added 0.5 M of 9-BBN in THF (2 mL, 1.0 mmol). The reaction is allowed to stir at room temperature for 1 hr, whereupon a 1M solution of NaOH (2.5 mL) is added. The organic layer is diluted with 10 mL of diethyl ether and the aqueous layer is removed. The organic layer is washed 3×10 mL with 1M NaOH, followed by 2×10 mL water and 2×10 mL saturated NaCl solutions. The organic layer is then dried over Na2SO4 and the solvent is removed under reduced pressure to afford 1-(3-hydroxy-propyl)-1H-indole-5-carbaldehyde.
