Yield	Reaction Conditions	Operation in experiment
71.4%	With hydrogen; sodium acetate In ethanol for 18 h;	A 2 L Parr bottle was charged with sodium acetate (28.6 g, 349 mmol), 10percent Pd(OH)₂/C (5.0 g, 7.12 mmol) and 3-(2,4-dibromophenoxy)pyridin-2-amine (60 g, 174 mmol) in IL EtOH and placed under 35 psi hydrogen for 18 hours. The reaction was filtered through a plug of celite and then concentrated. The residue was redissolved in CH₂Cl₂ and washed with aqueous sodium bicarbonate. The organic layer was dried over sodium sulfate, filtered and concentrated. The dark residue was dissolved in EtOAc and charcoal added. The mixture was stirred for 30 minutes then filtered though a plug of celite. The crude material was triturated with 4:1 (EtOAc and hexanes) to afford 3-phenoxypyridin-2- amine (23.2 g, 71.4percent yield).

Yield	Reaction Conditions	Operation in experiment
95.6%	With bromine; In chloroform;	A 2 L round-bottomed flask was charged with <strong>[391906-83-5]3-phenoxypyridin-2-amine</strong> (30.5 g, 163.8 mmol) and chloroform (1 L). Bromine (8.392 ml, 163.8 mmol) was added slowly and stirred for 30 min. The reaction was poured into saturated aqueous NaHCO3 and extracted with dichloromethane (2 x 400 mL). The organic layer was dried over sodium sulfate, filtered and concentrated in vacuo to afford 5-bromo-<strong>[391906-83-5]3-phenoxypyridin-2-amine</strong> (41.5 g, 95.6% yield) as a brown solid. 1H NMR (CDCl3) d ppm 7.88 (d, J = 2.0 Hz, 1H), 7.39 (m, 2H), 7.18 (m, 1H), 7.07-7.00 (m, 3H), 4.79 (br s, 2H); MS (acpi) m/e 265.2, 267.2 (M+H)+.
77.74%		3-Phenoxypyridin-2-amine (20.50 g, 110.1 mmol) was placed in acetic acid (50 mL) and cooled to 0 C. Bromine (d 3.12) (7.049 mL, 137.6 mmol) was slowly added and the reaction mixture was stirred for 1 hour. The reaction mixture was poured onto saturated sodium bisulfite and ice and allowed to sit overnight. Solids were removed by filtration and washed with water to give pure 5-bromo-<strong>[391906-83-5]3-phenoxypyridin-2-amine</strong>. The filtrate was then extracted with CH2Cl2 several times, combined, and washed with water. Organic layer was dried, filtered, and concentrated. The residue was purified by silica gel (5-20% EtOAc in hexanes) to give additional 5-bromo-<strong>[391906-83-5]3-phenoxypyridin-2-amine</strong> (total yield: 22.69 g, 77.74% yield).
70.70%		A 3 L flask was charged with <strong>[391906-83-5]3-phenoxypyridin-2-amine</strong> (63.6 g, 342 mmol) and CHCl3 (1500 mL). The reaction was cooled to 0 0C and bromine (21.0 mL, 410 mmol) was added dropwise. The reaction was stirred for 1 hour. Another 1 mL of bromine was added and the reaction was poured into saturated aqueous NaHCO3 (1500 mL) and extracted with CH2Cl2. The organic layer was dried with sodium sulfate and 25 g charcoal. The mixture was filtered through Celite and concentrated in vacuo. The residue was dissolved in CH2Cl2 and passed through a plug of silica (IL) eluting with 30% EtOAc/Hexanes to afford 5-bromo-<strong>[391906-83-5]3-phenoxypyridin-2-amine</strong> (64.02 g, 70.70% yield).

Yield	Reaction Conditions	Operation in experiment
90%	With potassium carbonate; In 1-methyl-pyrrolidin-2-one; at 90.0℃;Inert atmosphere;	2.00 g (11.6 mmol, 1 equivalent) of Compound 14d, 10 equivalents of phenol, and 5 equivalents of potassium carbonate were stirred under an NMP solvent. The temperature was adjusted to 90 C., and a reaction was performed under a nitrogen atmosphere. After the reaction was terminated, the temperature was cooled to room temperature and a solid was formed by pouring HCl (aq) thereto. After the formed solid was separated from the solution through a filter, the solid was dissolved in a chloroform solution and extraction was performed by using water. After the remaining moisture in the organic layer was removed over anhydrous magnesium sulfate, the residue was concentrated through distillation under reduced pressure, and 1.94 g (yield 90%) of Compound 20e could be obtained through column purification.

To this solution, 0.19 mL 37% formaldehyde was added and stirred at 5-10 °C for about 10 min. Then a solution of substituted aminopyridine (1.0 equiv) in methanol (10 vol) was added dropwise to resulting reaction mixture at the same temperature with vigorous stirring for 1 h. The reaction mixture was then introduced to the microwave oven and was irradiated for 8-9 min at 60-65 °C (300 W) while monitoring the course of reaction by TLC (using dichloromethane: methanol, 9:11). Then after reaction mass was kept overnight at room temperature. The resulting solid was collected by filtration, washed with cold petroleum ether (2 X 2.5 mL), dried and recrystallized from ethanol to obtained pure (3a-e) & (4a-e).
