Versuchsvorschrift

Quinoline-6-carboxylic acid 4-benzylamino-benzylamide described in Preparation Example E+-3 (30 mg, 82 μmol), formalin (9 μl, 115 μmol), triacetoxy sodium borohydride (25 mg, 115 μmol) and acetic acid (several drops) were suspended in tetrahydrofuran (1 mL), and the solution was stirred at room temperature for 4 hours. An aqueous solution of saturated sodium bicarbonate was added to the reaction suspension at 0° C., which was then extracted with ethyl acetate, the organic layer was washed with brine and dried over anhydrous magnesium sulfate. The solvent was evaporated in vacuo, purification was carried out using thin layer NH silica gel chromatography (hexane:ethyl acetate=1:1), and the title compound (11 mg, 28 μmol, 35%) was obtained as a white solid.
