Procedure

1.37 mL (9.9 mmol) of Et3N and 0.5 mL (4.5 mmol) of 5-bromovaleric acid chloride are added to a solution of 1 mL (4.0 mmol) of the decahydroquinoline in AcOEt. The resulting solution is kept under stirring for 18 h at rt. The solution is then washed with water, and the water re-extracted twice with AcOEt. The pooled organic phases are sequentially washed with 5% solution of NaHCO3, 1N HCl and saturated ammonium chloride solution. Finally the organic phase is dried over anhydrous Na2SO4, it is filtered and the solvent is evaporated under reduced pressure. 1.2 g of a yellow oil, which was used without subsequent purification, are obtained.
