실험 절차

Ethyl 4-(4-amino-3-fluorophenoxy)-2-aminopyridin-3-yl-carbamate (6a) (480 mg, 1.6 mmol) was dissolved in dry THF (8 mL) and cooled at 0° C. Sodium hydride (60% in mineral oil, 80 mg, 2.0 mmol) was added, and the reaction mixture was stirred for 40 minutes at 0° C. Methyl iodide (130 μL, 1.8 mmol) was added at 0° C. The ice bath was removed, and the mixture was stirred at room temperature for 18 hours. The solvent was evaporated and the residue partitioned between DCM and distilled water. The organic layer was dried and evaporated, and the residue washed with diethyl ether to afford the title compound as a brown solid.
