Reaction Steps

A mixture of 5-bromo-2-(trifluoromethyl)pyrimidine (900 mg, 3.97 mmol), methyl 2-propenoate (0.533 mL, 5.95 mmol), Pd(OAc)2 (44.5 mg, 0.198 mmol), tri-o-tolylphosphine (241 mg, 0.793 mmol) and TEA (1.105 mL, 7.93 mmol) in DMF (6 mL) under argon was heated at 130° C. for 1 h. After cooling to room temperature, water (40 mL) was added to the reaction mixture and then extracted by EA (3×50 mL). The organic phase was washed with brine, dried over MgSO4 and evaporated in vacuo to afford the title compound (900 mg, 3.88 mmol, 98% yield) as a yellow solid. LCMS: rt=2.67 min, [M+H+]=233
