To a solution of 3-benzyl-2-iodoquinoline 11 (1 eq., 1.45 g) in dry tetrahydrofuran (20 ml) at −78° C., was added isopropyl magnesium chloride (3 eq., 6.3 ml). The color of the solution was changed from green to orange in 1 h. Isobutyraldehyde 12 (3 eq., 1.15 ml) was added and the reaction mixture was allowed to warm up to room temperature and stirred for another hour. Ethyl acetate was added. The organic layer was washed with saturated sodium bicarbonate, saturated sodium chloride, dried over magnesium sulfate, filtered and concentrated. The crude material was purified by flash chromatography to yield 150 mg of 1-(3-benzylquinolin-2-yl)-2-methylpropan-1-ol 13.
