Reaction Steps
(Step 3) A solution of 2-amino-5-chloronicotinamide (202 mg) and methyl 4-chloro-2-bromomethylbenzoate obtained in Step 2 (470 mg) in DMF (5 ml) was stirred overnight at 90° C. The mixture was allowed to cool to room temperature, ethyl acetate was added, and the precipitated crystals were collected by filtration. The obtained crystals were recrystallized from ethanol and ethyl acetate to give the title compound (78 mg).
