YieldReaction ConditionsOperation in experiment
59% 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.
