Procedure

Phenyl isoquinolin-1-ylcarbamate (80 mg, 0.30 mmol) and (2-(4-methylpiperidin-1-yl)-6-(trifluoromethyl)pyridin-3-yl)methanamine (87 mg, 0.32 mmol) was dissolved in dimethyl sulfoxide. Then triethylamine (0.08 mL, 0.61 mmol) was added to it. The mixture was stirred at room temperature for 12 h. The reaction mixture was diluted with water and extracted with ethyl acetate. The organic layer was concentrated under reduced pressure. The crude was purified by column chromatography to give 1-(isoquinolin-1-yl)-3-((2-(4-methylpiperidin-1-yl)-6-(trifluoromethyl)pyridin-3-yl)methyl)urea (example compound 20) (46 mg, 34%).
