実験手順
Under an argon atmosphere 0.69 mL (6.87 mmol) borane-pyridine complex are added to a solution of 500 mg (1.72 mmol) 6-bromo-2-pyrrolidin-1-ylmethyl-quinoline (see 3.45b) in 10 mL acetic acid at RT. The mixture is stirred for 7 h at RT, again combined with 0.35 mL (3.46 mmol) borane-pyridine complex and stirred for another hour at RT. It is cooled to 0° C. and the solution is made basic with 8% NaOH solution. The aqueous phase is extracted with EtOAc and the solvent is eliminated i.vac. The residue is taken up with water and acidified with 12% HCl. The aqueous phase is extracted with EtOAc and then made basic with 20% NaOH solution while cooling with ice. The aqueous phase is extracted with EtOAc. The organic phase is dried over MgSO4 and the solvent is eliminated i.vac.
