Reaction Steps

2-Chloro-5-fluoropyrimidine (0.443 ml, 3.58 mmol), 3-methyl-5-(1,3-thiazol-5-yl)aniline (682 mg, 3.58 mmol), PdOAc2 (80 mg, 0.358 mmol), Xantphos (311 mg, 0.538 mmol), and cesium carbonate (2336 mg, 7.17 mmol) were combined in a flask and degassed with Argon. Dioxane (12 mL) was added and the mixture was degassed with Argon for 5 min. The mixture was then heated to 100° C. for 2 h. The reaction was cooled to room temperature, diluted with brine and EtOAc. The layers were separated and the aqueous portion re-extracted with EtOAc. The combined organics were dried over Na2SO4, filtered and concentrated in vacuo. Purification via silica gel flash chromatography (0-40% EtOAc:CH2Cl2) afforded 5-fluoro-N-[3-methyl-5-(1,3-thiazol-5-yl)phenyl]pyrimidin-2-amine (947 mg, 92%) as a beige solid. MS ESI: [M+H]+ m/z 287. rhSYK activity=++.
