Reaction Steps

To a suspension of 3-(8-(methoxycarbonyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinolin-2-yl)benzoic acid (63 mg, 0.19 mmol) in dichloromethane (5.0 mL) was added N-hydroxybenzotriazole (37.6 mg, 0.28 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide.hydrochloric acid (106.7 mg, 0.56 mmol), followed by 4-methylmorpholine (56.3 mg, 0.56 mmol) and the resultant mixture was stirred at room temperature for 1 h., then 1-methylpyrrolidin-3-amine (27.9 mg, 0.28 mmol) was added to the flask and the reaction mixture was stirred for an additional 1 h. LC-MS showed the reaction was complete. The reaction was quenched with water and separated. The aqueous layer was extracted with dichloromethane (twice) and the combined organic layers were washed with 5% sodium hydroxide aqueous solution (twice) and water (3 times), dried over anhydrous magnesium sulfate. Removal of the solvent in vacuo gave 76 mg of methyl 3,3-dimethyl-2-(3-(1-methylpyrrolidin-3-ylcarbamoyl)phenyl)-1,2,3,4-tetrahydroquinoline-8-carboxylate as a white solid, which was used in next step without further purification.
