Versuchsvorschrift

To a solution of phenyl 6,7-dihydro-5H-cyclopenta[b]pyridin-3-ylcarbamate (E) (80 mg, 0.31 mmol) in DMF was added DMAP (38 mg, 0.31 mmol) and (2-(4-methylpiperidin-1-yl)-6-(trifluoromethyl)pyridin-3-yl)methanamine (F) (90 mg, 0.33 mmol) at room temperature. The reaction mixture was heated to 50° C. for 14 h. TLC showed complete consumption of starting material. The reaction mixture was diluted with water and extracted with EtOAc. The organic part was washed with water and brine. The organic layer was dried over MgSO4 and concentrated under reduced pressure. The crude was purified by column chromatography to give pure 1-(6,7-dihydro-5H-cyclopenta[b]pyridin-3-yl)-3-((2-(4-methylpiperidin-1-yl)-6-(trifluoromethyl)pyridin-3-yl)methyl)urea (example compound I) (104 mg, 76%).
