Reaction Steps

200 mg (0.85 mmol, 1 eq) 2-chloro-5-[(2-methyl-1,3-thiazol-4-yl)ethynyl]pyrimidine, 50 mg (0.043mmol, 0.05 eq) tetrakis(triphenylphosphine)palladium(0), and 2 mL of 0.5 M cyclohexylzinc bromide in THF (1 mmol, 1.1 eq) were combined. The reaction mixture was heated at 150° C. in the microwave for 5 min, quenched with pH 10 PBS, extracted with DCM. Silica gel chromatography (gradient 10% to 40% EtOAc/Hexanes) gave 2-cyclohexyl-5-[(2-methyl-1,3-thiazol-4-yl)ethynyl]pyrimidine (L-001152744). LC-MS calculated for C16H17N3S 283, observed m/e 284.1 (M+H)+.
