Reaction Steps
Sodium hydride (60% dispersion in mineral oil, 0.38 g, 9.48 mmol) was washed 3x with hexanes then a solution of 2-cyclohexylamino-5-nitropyridine (1.88 g, 8.5 mmol) dissolved in dimethylformamide (20 mL) was added. After stirring for 30 minutes at 22° C., the reaction mixture was cooled to 0° C. and methyl iodide (0.55 mL, 8.9 mmol) was added. The solution was stirred for 1.5 hours at 0° C. followed by quenching with saturated aqueous NH4Cl. The reaction mixture was diluted with ethyl acetate and extracted 5x with water (200 mL), saturated NaCl, dried over Na2SO4 and concentrated in vacuo oil was chromatographed on SiO2 using 2:1 hexanes/ethyl acetate as eluent.
