Yield	Reaction Conditions	Operation in experiment
68.2%	With dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; caesium carbonate; In 1,4-dioxane; water; at 85℃; for 17h;Inert atmosphere;	Preparation 92A: 3-Fluoro-4-(p rimidin-5-yl)picolinonitrile[00317] A vial containing a mixture of <strong>[669066-35-7]3-fluoro-4-iodopicolinonitrile</strong> (1.25 g, 5.04 mmol), pyrimidin-5-ylboronic acid (1.249 g, 10.08 mmol), and cesium carbonate (3.45 g, 10.58 mmol) in dioxane (Ratio: 2.0, Volume: 10.18 ml) and water (Ratio: 1.000, Volume: 5.09 ml) was degassed with N2 for 5 min, then PdCl2(dppf)-CH2Cl2Adduct (0.218 g, 0.267 mmol) was added. The solution was heated at 85 C for 17 hr, and then allowed to cool to room temperature. The reaction was quenched with water. The reaction mixture was diluted with EtOAc. The layers were separated and the aqueous phase was extracted with EtOAc (3X). The organic phases were combined, dried over Na2S04, filtered, and concentrated to afford a brown residue. The crude material was purified by MPLC (80 g column, 60 mL/min, 30-100% EtOAc in hexanes) to give the title compound (695 mg, 3.44 mmol, 68.2% yield) as a pink solid. ESI MS (M+H)+ = 201.1.

K3PO4 solution (0.67 mL, 1.3 mL/mmol). The flaskwas stirred at ambient temperature for ~5 min and then transferred to a pre-heated oil bath at 100 C. Heating was continued for 38 h,after which the mixture was cooled to ambient temperature. Themixture was neutralized (pH ~ 7) with 0.5M aq. HCl. The mixturewas evaporated till dryness re-suspended in MeOH and evaporated(three times). Next, the mixture was adsorbed onto Celite (fromMeOH) and eluted over a short silica pad (~5 cm) with 20% MeOH/DCM. The liquid was evaporated in vacuo and purified by columnchromatography 5/20% MeOH/EA. 18 was isolated as a yellowsolid (0.045 g, 0.13 mmol). Yield 26%.

methyl 3,5-diamino-6-(pyrimidin-5-yl)pyrazine-2-carboxylate [ No CAS ]

Yield	Reaction Conditions	Operation in experiment
35%	With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In methanol; toluene;Inert atmosphere; Reflux;	General procedure: <strong>[1458-01-1]Methyl 3,5-diamino-6-chloropyrazine-2-carboxylate</strong> 2 (1 eq.) was combined with K2CO3 (10 eq.), the appropriate (het)aryl boronic acid (1.5 eq.) and Pd(PPh3)4 (5 mol%) in a two-neck round bottom flask. The flask was connected to a condenser and purged with nitrogen. A 4:1 mixture of anhydrous toluene: MeOH (60 mL) was added via syringe and the reaction mixture was heated at reflux for 0.5-18 h. The mixture was allowed to cool to room temperature and filtered through Celite (10 x 3 cm, eluting with 3 x 20 mL EtOAc). The filtrate was evaporated to dryness and the residue purified by silica gel flash column chromatography using EtOAc/pet spirit.
