Participants

Reaction Steps

A 18-mL vial was charged with [2-(5-chloro-2-thienyl)-5-ethyl-6-methyl-pyrimidin-4-yl]trifluoromethanesulfonate (39 mg, 0.1 mmole) and 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (22 mg, 0.1 mmol) and DMSO (0.5 ml). The resulting mixture was stirred under Ar for 3.5 hr. After cooling to room temperature, water was added to the mixture (5 ml). The precipitate was collected by filtration and the crude product was purified by chromatography on silica gel using hexane/DCM (4:1) followed by 2% of methanol in DCM as eluent to afford the title compound, containing impurities, which was forward to the next step without any further purification (10.3 mg, 23% yield).
