Then 1-methylazetidin-3-amine (30.5 mg, 0.35 mmol) was added to the flask and the reaction mixture was stirred for an additional 60 min, LC-MS showed the reaction was complete. The reaction was quenched with water, separated, and the aqueous layer was extracted with dichloromethane (twice). The combined organic layers were washed with 2% sodium hydroxide aqueous solution (twice) and brine (3 times), dried over anhydrous magnesium sulfate. Removal of the solvent in vacuo gave 129 mg of methyl 3,3-dimethyl-2-(3-(1-methylazetidin-3-ylcarbamoyl)phenyl)-1,2,3,4-tetrahydroquinoline-6-carboxylate as a white solid, which was washed with ether to afford 103 mg desired product as a white powder, yield: 85.8%.
