Reaction Steps
A degassed solution of 3,5-dichloro-6-methyl-1,2,4-triazine (151 mg, 0.9 mmol), 4-(benzyloxy)-3-methoxybenzene boronic acid (236 g, 0.9 mmol), tetralis(triphenylphosphine)palladium(0) (55 mg, 0.05 mmol) and tripotassium phosphate (249 mg, 1.2 mmol) in dimethoxyethane (5 mL) was heated at reflux for 24 h. Upon cooling to room temperature the solution was diluted with CHCl3 and filtered through Celite®. The filtrate was concentrated in vacuo and the product purified by column chromatography using ethyl acetate-hexane (25:75) as eluent to furnish (75 mg, 22%).
