Versuchsvorschrift

To a solution 3-bromo-5-methoxyquinoline (2.37, 10 mmol) prepared in stage B in dried THF (35 mL) is added a solution of isopropylmagnesium chloride (16.6 mL, 30 mmol) at −78° C. The solution is stirred at −78° C. under nitrogen atmosphere for 3 hours. Menthyl sulfinate (8.8 g, 30 mmol) is added and the resulting solution is stirred for a further 24 hours. The reaction mixture is then hydrolysed with saturated aqueous NH4Cl solution. After extraction of the aqueous phase, the combined organic layers are dried (MgSO4), evaporated giving the title compound.
