Versuchsvorschrift

To a solution of methyl 2-(4-aminophenyl)-3,3-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (100 mg, 0.32 mmol) and N,N-diisopropylethylamine (0.11 mL, 0.64 mmol) in dichloromethane (5 mL) was added freshly prepared picolinoyl chloride (56 mg, 0.35 mmol) with ice cooling. Upon completion of addition, the resultant deep blue solution was allowed to warm back to room temperature and stir overnight. LC-MS showed the reaction was complete. Solvent was removed in vacuo and the residue was purified by preparative Thin layer chromatography to afford 70 mg of methyl 3,3-dimethyl-2-(4-(picolinamido)phenyl)-1,2,3,4-tetrahydroquinoline-6-carboxylate as a white solid. Yield: 52%. MS (ESI+APCI) M+1=416.20.
