To a solution of 1-(3-benzylquinolin-2-yl)-2-methylpropan-1-amine 14 (91 mg, 1 eq.) in ethanol (2 ml), was added hydrazine (10 μl, 1.5 eq). The reaction was stirred at room temperature for an hour but very little product was detected. It was heated to 40° C. for 3 h and the 27% starting material was detected. More hydrazine (10 μl, 1.5 eq) was added and the reaction mixture was stirred for another half hour. The precipitate was filtered through a PTFE filter and washed with more CH2Cl2. The filtrate was concentrated and the crude product was purified by flash chromatography to yield 31 mg of 1-(3-benzylquinolin-2-yl)-2-methylpropan-1-amine 15 as clear oil.
