Participants

Reaction Steps

A mixture of 2-(4-bromophenyl)-5-methylpyrimidine 78 (250 mg, 1.008 mmol), palladium acetate (50 mg), cesium carbonate (400 mg, 1.23 mmol), (S)-2-methyl piperazine (200 mg, 2 mmol) and 2-Di-t-butylphosphino)-biphenyl (50 mg, 0.167 mmol) was stirred in dioxane:water (10 ml, v/v 5:1) at reflux temperature for 4 hours. The reaction was cooled, diluted with MeCl2 (100 ml) and H2O (50 ml). The organic layer was separated, dried (MgSO4), filtered and solvent evaporated. The residue was purified by chromatography eluting with 100% EtOAc then with 10% v/v MeOH/EtOAc/NH4OH yielding product 79 as a white solid. (220 mg. 81%) ESMS (MH, 269).
