Procedure

To a solution of tert-butyl (5-((1H-pyrazole-4-carboxamido)methyl)-4,6-dimethylpyridin-2-yl)carbamate (100 mg, 0.290 mmol) in acetone (2.5 ml) were added 2-(bromomethyl)-7-chloroquinoline (74.3 mg, 0.290 mmol) and K2CO3 (200 mg, 1.448 mmol). Reaction mixture was stirred for 5 h at 50° C. Reaction mixture was diluted with ethyl acetate and water. Phases were separated and organic layer was washed with brine, dried over sodium sulfate, filtered and evaporated to afford the title compound. HPLC (Method G) Rt=1.736 min, MS (Method V) [M+H]+=521.3.
