Reaction Steps

2-(4-Chloro-2-methyl-phenoxy)-5-aminopyridine (2.15 g, 9.16 mmol) was combined with powdered sodium hydroxide (1.46 g, 36.6 mmol), potassium carbonate (1.27 g, 9.16 mmol), tetrabutyl ammonium bromide (60 mg, 0.18 mmol) and toluene (10 mL) was stirred for 1 hour at 35° C. A solution of dimethyl sulfate (0.91 mL, 9.6 mmol) dissolved in toluene (5 mL) was added slowly. The mixture was heated at 35° C. for 20 hours. After cooling, the solids were removed by filtration and the solvent was concentrated in vacuo. The desired material was purified by chromatography on SiO2 using 30% ethyl acetate/hexanes as eluent. MS (m/z): 248/250 (M+H)+; C13H13N2OCl requires 249.
