Procedure

The reaction mixture of (S)-ethyl 2-(2-(3-bromophenyl)-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyacetate (12 mg, 0.025 mmol), 5-pyrimidineboronic acid (5 mg, 0.0375 mmol), 2N K2CO3 (60 μL), Pd(PPh3)4 (3 mg, 0.0025 mmol) in dioxane (1 mL) was heated at 120° C. in sealed tube. After the reaction was finished, the reaction was washed by sat. NaHCO3, extracted by EtOAc, the organic phase was dried over MgSO4, filtered, concentrated down and purified by silica gel column, eluting by 0-100% EtOAc in hexanes to give the product. LCMS-ESI+: calc'd for C32H30ClN3O3S: 572.2 (M+H+); Found: 572.2 (M+H+).
