Versuchsvorschrift

To a 0.23 M solution of 2-isopropylquinoline in trifluoroacetic acid in a Parr flask was added 0.1 equiv of PtO2. The suspension was set up on the Parr apparatus at 44 psi H2 overnight. After removal of the H2, CH2Cl2 was added, and the suspension was filtered through Celite. The solvent was removed under vacuum, and the residue was partitioned between EtOAc and saturated NaHCO3 solution. The organic layer was washed with H2O and brine, and was then dried over anhydrous MgSO4, filtered and evaporated to give the title compound as a tan colored oil.
