Reaction Steps

Prepared using General Procedure 10. A mixture of methyl 2-(5-(tert-butyl)thiophene-2-carboxamido)-2-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)acetate (320 mg, 0.71 mmol) and 5-bromo-2-iodopyrimidine (220 mg, 0.78 mmol) in THF (2 mL) and MeCN (2 mL) was treated with saturated aq. NaHCO3 (1600 μl, 1.40 mmol) and de-gassed (N2 bubbling). PdCl2dppf (26 mg, 0.04 mmol) was added and the mixture was heated at 120° C. for 30 min in a microwave reactor. The mixture was poured onto H2O (30 mL), acidified with AcOH and extracted with EA (3×15 mL). The combined organics were dried over MgSO4, evaporated, and purified by chromatography (EA/hexane with 1% AcOH) to provide 160 mg (46%) of 2-(4-(5-bromopyrimidin-2-yl)phenyl)-2-(5-(tert-butyl)thiophene-2-carboxamido)acetic acid as a white solid. LCMS-ESI (m/z) calculated for C21H20BrN3O3S: 473.0. found 474.0 [M+H]+, tR=2.68 min (Method 8).
