To a suspension of sodium hydride (60% dispersion in mineral oil, 46 mg, 1.1 mmol) in tetrahydrofuran (4 ml) was added 5-chloro-N-methylpyridin-2-amine (128 mg, 1.14 mmol) in tetrahydrofuran (5 ml) at room temperature and stirred for 30 min. The mixture was added methyl 2-(bromomethyl)-5-chlorobenzoate (250 mg, 0.95 mmol) in tetrahydrofuran (5 ml) at room temperature and stirred at 80° C. for 8 hr. After cooling to room temperature, the mixture was added water and extracted with ethyl acetate. The organic layer was dried over sodium sulfate and evaporated. The residue was purified by flush column chromatography on silica gel eluting with hexane/ethyl acetate (10/1) to afford 102 mg (33%) of the title compound:
