Reaction Steps

To a suspension of 3-(6-(methoxycarbonyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinolin-2-yl)benzoic acid (100 mg, 0.29 mmol) in dichloromethane (6.7 mL) was added N-hydroxybenzotriazole (59.7 mg, 0.44 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide.hydrochloric acid (169.7 mg, 0.88 mmol), followed by 4-methylmorpholine (89.5 mg, 0.88 mmol) and the resultant mixture was stirred at room temperature for 40 min. 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%.
